{{TOC}}
{{incomplete}}
==Explanation==
A {{w|distribution board}}, referred to as a "breaker box" here and also commonly referred to as a "fuse box", "breaker panel", "DB box", and many other names, is a metal box attached to a wall, usually in some maintenance area, containing multiple {{w|circuit breakers}} that distribute electricity to various parts of the building. A circuit breaker is an electrical switch, usually in the form of a small lever, which disconnects the circuit from the power source when opened. These breakers are designed to automatically open if too much electrical current flows through them. This is a safety measure to reduce the risk of damage and fire in the event of a short circuit or an overloaded line. These breakers can also be opened manually, deactivating the circuit to allow electrical work to be done.

In breaker boxes, each individual breaker is typically labeled to let the operator know what that breaker controls. Typically, the circuit controlled by each breaker will feed an intuitive set of connections: a certain room, or set of rooms, or possibly a set of related services (like overhead lights, or all the outlets on one floor). Some large appliances will have a dedicated circuit and breaker. However, in houses that have been rewired multiple times (or were poorly wired the first time), this can quickly become overcomplicated with seemingly random connections. Randall lives in Boston where much of the housing stock is from the late 1800s and early 1900s, and he is likely to live in a house with non-ideal wiring, which may have inspired this comic.

The comic satirizes these complex wiring setups, with multiple breakers "controlling" arbitrary things, including some that – in the classic style of xkcd – are puns on the word "breaker" or may be impossible to hook a breaker up to, getting progressively more absurd to the point of nullifying laws and "breaking" certain laws of physics. Typically, switches in a breaker-box have the same orientation of "on" and "off" direction. This particular setup appears to adopt the convention that all switches are on (or, possibly, that all are ''off'') when flipped towards the centre of the panel. Exactly which direction the switches are installed would be more obvious from coloration, markings or even relief details that would be manufactured into the switch subunits but which are not so fully depicted in the comic.

===Left column of switches===
; Kitchen lights

; Living room lights

; Porch lights

; Bathroom lights and one surprise mystery outlet somewhere
: The lights in the bathroom, but also a random outlet. It is not uncommon for the power supplies to bathrooms (and other rooms with water connections) to be on a separate circuit. This is because water can potentially cause a short circuit, resulting in the breaker opening, and separate circuits minimize the impact and makes the problem easier to locate. These are called "GFCI" or "GFI" (Ground Fault Circuit Interrupter [https://www.cpsc.gov/s3fs-public/099_0.pdf]) circuits.

: It is a standard to connect a bathroom outlet with another outlet also requiring a GFCI, such as basement or outdoors. Another option is that an electrician (or homeowner), having initially reserved an output from the box for such a limited use, may – while adding wiring – chooses to wire seemingly unrelated things into the same circuit. This may make sense (for example, an outlet near a non-bathroom sink or some other water source could reasonably be grouped with the bathroom), or it may simply be out of convenience from how long the wires needed to run (such as an outlet in the room adjacent to the bathroom). In either case, future residents and installers may not be informed of this, and therefore wouldn't realize that the outlet is grouped with that circuit.

; North-facing appliances
: Peculiar and a bit complex to execute. Here's how it might have been set up:
:# Install a breaker switch that is actually a mechanical switch to control a smart home automation instead of its normal function.
:# Replace relevant normal outlets with Wi-Fi-controlled smart outlets.
:# Use smart home software to create a custom group of all outlets that control all ''north-facing appliances.
:# Set up a software automation to selectively toggle this user-defined group of smart outlets when triggered. Adding a matching appliance to the house would require editing the automation.

: Alternatively, the switch may be physically wired only to outlets installed on a southern wall in the property (or ''all'' southern walls, for each room that requires them), and you'd ensure that everything connected to these exclusively north-facing outlets also faces directly away from the wall(s). The switch could also control appliances on the north-facing walls of the house. The word "north-facing" has a broad interpretation, as lax as northeast to northwest or as strict as {{w|Points of the compass#32-wind compass rose|north by east to north by west}}. It could also be as exact as perfect north, but this would render this breaker completely functionless unless an appliance happens to be ever-so-perfectly aligned.

; Bathtub drain light
: Bathtub drains typically do not have lights, but this breaker provides power to that and only that. Why it isn't already considered a "bathroom light" is unexplained (unless it's for the bit of the pipe that is ''external'' to that room). Perhaps it is a sub-menu of bathroom breaker, but then its position on the panel is unusual in that it isn't next to the bathroom breaker. It obviously cannot be the "surprise mystery outlet" already referred to earlier as being covered under the switch for the bathroom lights, much apart from it not being a socket/outlet.

; Appliances whose names contain the letter "F"
: Another odd and amusing specification. To make it work, one might use the "North-facing appliances" setup described above, but just with a different custom group of Wi-Fi-controlled smart outlets chosen to only control appliances with an "F' in their name. Some common household appliances (kitchen and elsewhere) that this switch might control:

:* coffee maker
:* refrigerator
:* freezer
:* fan
:* air fryer
:* food processor
:* waffle iron
:* fabric steamer
:* Wi-Fi router
:* fireplace (electric)

; Hot water heater
: A {{w|hot water heater}} is usually just a heater that creates (and typically stores) hot water. But given that the next breaker controls the "Regular water heater", this breaker might actually control a water heater that pointlessly heats water that is ''already'' hot. This is probably a joke about the fact that the common phrase "hot water heater" is [[1475: Technically|technically]] redundant, since the simpler term "water heater" is enough to describe a device that produces hot water, or misleading, since it's not the purpose of residential water heaters to heat water that is ''already'' hot. In some languages, "hot water" is a separate, single word, so "hot-water heater" can be accurate. One such example is Japanese, where "hot water" is simply referred to as "お湯" ("Oyu"), however this is taken a step further as "hot water heater" is referred to as "給湯器" ("Kyūtōki").

; Regular water heater
: The heater for regular water. In context with the switch above, this label presumes it's for a heater for heating water that is not yet hot (usually called a "hot water heater", hence the joke). Alternatively, if we assume that a ''hot water heater'' is for ''making'' hot water, this heater must be for making “regular water”, whatever temperature that may mean. Further still, the difference in these labels may be speaking to the nature of the heaters themselves - it could be the case that one of the heaters is abnormally hot to the touch, where the other is a "regular" temperature, but are otherwise both capable of heating water just fine.

; Outlets in rooms that it's normal to eat pizza in
: This controls every outlet in rooms that it's normal to eat pizza in, such as the dining room and kitchen and – depending on the "normal" habits of the inhabitants – other rooms such as the bedroom, bathroom, or living room (if not already covered by the "living room lights" switch above). Closets and single-purpose rooms such as the laundry room are presumably not included.

; High-pitched hum generator
: Controls a high-pitched hum generator. This is a call-back to [[1590: The Source]], which was released just over 8 years before this comic.

; The solution to the cryptogram below:
: Likely a pun on a "code breaker," something or someone that solves a code, such as Randall's cryptogram, a type of puzzle where a sentence has been encoded using a cipher, usually simple, and the goal is to determine the cipher and recover the original sentence from the encoded one. Randall has not actually written a cryptogram, simply making the label's text illegible to the audience. Alternatively, the identity of the electrical load sourced from this breaker can be found by solving the cryptogram. This switch could somehow enable or disable the code's solution, perhaps toggling its knowability or solvability or turning on a computer for solving cryptograms.

; Bugs
: Several interpretations are possible:
:* Disable all insect bugs in the house – as an efficient form of pest control – perhaps using ultrasonic emitters that drive away bugs (may be a reference to [[2753: Air Handler]]) – or perhaps the house contains noise machines that play sounds of insects or other ways of simulating insects.

:* Disable power to all covert listening devices, which would be able to be switched off if wired into the house's electrical grid.

:* Disable the whole global category of bugs (insects, arachnids, and other small arthropods), in which case we'd have no more pests and we'd reduce disease like malaria and {{w|Lyme disease}}! Of course, food webs would also collapse, and our world would be overrun with waste.

:* Disable all software bugs in the house. Though it's unlikely that it's what Randall is referring to, computer bugs switches actually exist. It's a feature in some video game emulators to either run an unofficial patched version or to stay true to the original system, for example to allow bug-exploit speedruns of a video game.

:* All or any of the above

===Right column of switches===

; A whirring fan you didn't realize was on until now
: Fans generally produce a steady, low-level 'white' noise that people generally stop noticing. When such a fan is turned off, the absence of that noise is quickly noticed. Alternatively, the fan could be somewhere that cannot be heard, with the label on the switch serving as the only reminder of the fan's existence. Shutting down a fan that you didn't realize was running could be worrisome for a couple of reasons: it could be serving an important function (like HVAC or server cooling) and cause a problem when it's off, or it may be a fan that wasn't supposed to be running, but had been for some time without being noticed.

; Dishwasher
: A dishwasher may find itself with a separate circuit breaker for a few reasons. Commercial-grade dishwashers are often high-load appliances that require more power (incorporating powerful heating units and pumps). Residential-grade dishwashers may not be as energy-intensive, but if the house wasn't originally built with a dishwasher in mind, it is likely new wiring had to be added during its installation, resulting in a breaker that exclusively controls the dishwasher. Though what "dishwasher" actually means may depend on what the "dishes" of the next switch might be, and thus what additional device may be required to ensure they remain clean. Even at the more trivial end of the interpretation (though not then explaining the following "dishes"), a busy restaurant might have an employee section equipped exclusively for the dishwashing role and separately supplied with power in a similar manner to that suggested for the bathroom.

; Dishes
: Likely a pun on "breaking" dishes. Of course, dinnerware and dishes are usually not powered devices and wouldn't require a circuit breaker at all; discovering they need their own circuit breaker separate from their dishwasher is a spoof of many common circuit breaker frustrations. Lastly it's also possible the switch powers/controls two or more satellite dishes.

; Hallway lights
: The lights in the hallway or hallways.

; Hallway outlets
: The outlets in the hallway or hallways, presumably the same as the "Hallway lights" hallways. A common confusion when turning off breakers is separate wiring for outlets and lights in the same room. Though having the room go dark is a good mnemonic that it is unpowered, it is not a guarantee, and indeed, wiring them separately allows working on the outlets without having to do it in the dark.

; Hallway floors
: Yet another breaker for the hallways, presumably the same hallways as the previous two breakers, adding more confusion and frustration. This breaker has several potential interpretations:
:# A master switch for all floors (stories) in the building which include hallways, e.g. the guestroom areas in a hotel, whilst possibly excluding the lobby and service levels
:# Outlets in the floor
:# Electric underfloor heating (heated bathroom floors are a feature in some houses)
:# Electrification of the floors – not common outside of horror and heist movies
:# Disabling all floors entirely, so everything resting on the floors falls through

; Social media
: This breaker also has several potential interpretations of "taking a social media break" or "turning off social media":
:# 'Digital detoxes', where someone says "I'm going to take a social media break" and intends to deny themselves access to all their social media apps.
:# A switch for a parent to turn off all social media entering the house to protect their kids and themselves, which references a type of specialized content filter available through Wi-Fi router settings, not traditionally a breaker box.
:# A callback to [[908: The Cloud]]. Since most social media platforms are centralized services, it would be theoretically possible to hook up a switch to the main power supply of every server building at once, given some extremely long wires, a breaker capable of handling the abhorrently massive electric load, and agreement from every social media provider.([[1439|optional]])
:# The theoretical desire by some to "turn off social media" for the world due to its harmful effects on society. As someone who lived before social media and saw its spread over two decades, Randall may be ruing the impacts of social media on civilization and channeling his desire to put the genie back in the bottle.
:# Potentially a play on the phrase “breaking the internet”, meaning going viral on social media, though "breaking social media" is not an idiom.

; State law
: This and the next two items are a pun on "breaking the law". Taken literally, it would either disable enforcement of State Law or nullify every single one, creating a state of lawlessness similar to the premise of the popular movie, "The Purge". It's unclear if this refers to Randall's state of Massachusetts or State Law as a general concept. If the switch simply nullifies State Law within the confines of the house, that would make the home a place where State Law could be broken without consequence.

; Federal law
: An extension of the previous entry. When discussing legal matters (taxes, regulations, etc.) it's not uncommon for state and federal authorities to issue their own statutes, often labeled "state" and "federal" respectively. The ramifications of nullifying every US Federal law are immense. Disabling Federal Law while keeping State Law would theoretically fulfill the goals of the "States Rights" advocates, groups of conservatives across US history aiming to return Federal power to the States.

; Second law of thermodynamics
: The {{w|second law of thermodynamics}} means that things naturally move from order to disorder over time. It also says you can't take heat from a place that's cooler and use it to make a place hotter than the cooler place, unless you use some energy to do it. In short, without adding energy, only the hotter place can warm up the cooler one. This law of physics was also explored in the What If? article [https://what-if.xkcd.com/145/ Fire From Moonlight].

; Friction
: {{w|Friction}} is the resistive force that opposes the relative motion or tendency of such motion of two surfaces in contact. Disabling friction would mean that all objects slide forever, and would destroy several things as well as make it much more difficult to move around and create energy. Being in a frictionless environment (and a vacuum, as physicists love...) was the subject of [[669: Experiment]].

; Gravity
: {{w|Gravity}} is a natural force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers. Turning gravity off would have extremely dangerous effects, such as the loss of the atmosphere into space, all items being flung away from the Earth, and, perhaps most dangerous, the complete destruction of the planet. Of course, if this switch is turned off, it may simply mean that objects within the house itself are no longer subject to gravity. This would be '''''far''''' less cataclysmic, and as a bonus, this would make it very different when moving around the house, making it easier to get to higher areas, and move objects, though impossible to place them without some other force being applied, and could prove to cause some problems once the breaker is turned back on, especially for things under said objects.

; Circuit breakers
: Possibly the "master" breaker, controlling the main circuit that supplies power to all other circuit breakers. However, given the other surreal things this breaker box controls, turning it off may possibly make it impossible to turn it on ever again as the switch will no longer function once switched off (i.e.: If this was turned off, it would presumably turn off the functionality of the circuit breaker itself, if it was wired to include itself). Another interpretation is that turning off this breaker should supposedly make this breaker not able to control the power, which leads to a situation similar to the liar's paradox.

: Moreover, if this circuit breaker disables all circuit breakers everywhere, it would result in global infrastructure collapse, halting essential services, including transportation, healthcare, and communication, and leading to widespread chaos. Note that it might be a perfectly valid label if it refers to multiple subsidiary 'boxes', cascaded off this particular one, each containing one or more additional breakers for convenience or safety. e.g. units dedicated to a shed, garage or workshop room which save the need to traipse all the way to this box's utility cupboard location in the event of an otherwise easily resolved power issue.

===Title text===

The title text is about {{w|causality}} and how to use this (unseen, located elsewhere) breaker along with the last shown switch that (de)powers the illustrated box. Causality, in its simplest form, is the process of cause and effect, meaning that everything that happens only happens because something caused it to happen - in other words, every event is an effect caused by another event. For example, a bag of chips can't just fall onto the floor for ''literally'' no reason - it has to be caused by some other event, such as someone smacking it or a gust of wind blowing it down.

Turning off the circuit breaker using the CIRCUIT BREAKERS switch may lead to a loop, if the disabled breaker can no longer disable itself, leading to it turning back on, etc. Alternatively, turning off the CIRCUIT BREAKER switch might be a one-way street. Turning the CAUSALITY switch from OFF back to ON might be unlikely to do anything if the circuit breakers upstream of it have been fully deactivated. The separation of cause and effect would ostensibly take precedence over the current switch setting. Turning off CAUSALITY first would prevent either the loop or the permanent disabling of circuit breakers, but would also have many other side effects, including letting switches potentially serve power even if there is no power being served ''to them'', or even spontaneously switching (on or off) without any intervention or reason.

The 'warning', from an electrician, could even be to locate the nominally ''off'' CAUSALITY switch in order to turn it ''on'', or else all other intended effects will possibly not end up being actually actioned. Either way, whether or not turning on/off causality would change the state of causality (at one stage or other being rendered ineffectual) is an exercise left for the reader.

1920: Emoji Sports

2025-08-17T08:16:37Z

2001:4450:813D:C800:3D62:5962:E748:B3F9: /* Explanation */

{{comic
| number = 1920
| date = November 24, 2017
| title = Emoji Sports
| image = emoji_sports.png
| titletext = No horse has yet managed the elusive Quadruple Crown—winning the Kentucky Derby, the Preakness, the Belmont Stakes, and the Missouri Horse Hole.
}}

==Explanation==

This comic, as the heading indicates, arbitrarily selects emoji and uses them to make up very bizarre sports. Although some of these might be completely normal, most of them take things to a completely absurd level.

The title text is a reference to the {{w|Triple Crown of Thoroughbred Racing (United States)|Triple Crown}}, which is an highly prestigious award given to a three-year-old thoroughbred horse who wins the {{w|Kentucky Derby}}, the {{w|Preakness Stakes}}, and the {{w|Belmont Stakes}}, the first three of the four listed events. The joke is that if Horse Hole was a real sport, then one who won a major competition for it, the Missouri Horse Hole, in addition to the three main horse racing events, would win a "Quadruple Crown".

''Please note that some emoji may not be supported by your browser, in which the emoji will appear as a black rectangle, and if there is a male/female version of the emoji, a male/female sign will appear next to the rectangle.''

|Lavaball
|Sets the sport of water polo around or inside an active volcano. If the water is simply replaced with lava, the players would asphyxiate from the toxic fumes long before they burned to death in the molten rock. If a typical pool of water is involved, the introduction of lava would cause rapid evaporation and the release of {{w|Chlorine#Use_as_a_weapon|chlorine gas}}, which is destructive to living tissue. In any case, this game is not a good idea.{{Citation needed}}

|Bladeball
|Using a fencing foil to hit a ball would be rather inefficient. There is however an actual sport combining ball sport and fencing called {{w|Jugger}}.
|-
|💃💃⚽
|Fancyball
|Soccer played in high heels and dresses would be a problem for both kicking and running, with the grassy terrain exacerbating these issues, and these would lead to frequent injury.{{Citation needed}} The name is likely a pun on "fancy ball", a dance party where people are in fancy clothing.{{Citation needed}}
|-
|🕳️🏇🏇🏇
|Horse hole
| Jockeys ride their horses into a large pit. Needless to say, such a sport would constitute blatant animal abuse; the ensuing fall would seriously injure competing equines (as well as their jockeys if they don't bail out beforehand). If the horse's self-preservation instinct kicks in before reaching the edge, the jockey will likely be severely injured in the process, an outcome which would likely garner a lot less pity. Both this segment and the title text may relate to Episode 354 of ''{{w|My Brother My Brother And Me}}'', "Beanfreak", where a potential punishment for losing horses in a race is described as a trapdoor leading to a "pony pile" beneath the track. (Many of the podcast's episodes deal with horse racing and horse behavior, including some impassioned conversations on the performance of specific horses and the unregulated nature of the widely recognized Triple Crown achievement.)
|-
|🔪🏀⛏️
|Basketball shredding
|The apparent point of this sport is to compete to destroy basketballs as quickly and/or as thoroughly as possible. There is some transgressive appeal in mistreating sports equipment, but hardly enough to keep a captive audience.
|-
|🥚🔭🕵️‍♀️
|Eggspotting
|This could be a combination of {{w|Egg_hunt|egg hunting}} and {{w|birdwatching}}. The emojis may imply that said eggs would have to be found alone in nature, as if they were wild animals, though it might be spotting of eggs of the wild animals in their nests. If the latter is true, the humor arises from the situation being like a form of pre-emptive birdwatching, as the eggs will eventually hatch into birds, and such an activity might be considered easier, or "beginner-level", birdwatching, due to the eggs remaining in one place.
|-
|⛷️🐊
|Alligator jumping
|An unusual combination of attributes, and to get the alligators to adapt to a cold environment might be a challenge. It may be related to the similar sport of {{w|Jumping_the_shark|shark jumping}}.

|Tinkerball
|Playing badminton with a fairy, named after {{w|Tinker Bell}} as a pun. Likely to injure the fairy, and such an activity runs the risk of the fairy flying away to escape the abuse. Fairies are not known to exist in the real world.{{Citation needed}}
|-

|Hedgehog curling
|Hedgehogs are not ideal projectiles for sports,{{Citation needed}} as {{w|Alice's Adventures in Wonderland}} has already demonstrated, and such an idea would be considered animal abuse on top of the impracticality. Nonetheless, hedgehogs are technically skilled at curling...their bodies.
|-
|🗜️🍔
|Burger clamping
|Perhaps a challenge to fit a tall burger into a bite-sized height, though said clamp would probably be more likely to pierce the burger than to flatten it.
|-
|👩‍🚀🏹🛰️
|Consequence archery
|Archery on a space station could cause damage to its structure leading to the potentially explosive decompression of the space station, and necessitate the evacuation of the astronauts aboard. If played outside, stray arrows could still cause a disaster by setting space debris into motion or by hitting space vessels or equipment. Another dangerous consequence of shooting an arrow while floating in space without a jetpack would be that the shot propels the astronaut in the opposite direction of the arrow, setting them off to drift away helplessly into space. Alternatively, the goal may be to hit satellites which would imply the consequence part being the resulting legal action accompanying a high score unless you wait for them to deorbit naturally in which case the consequence part would be everything associated with being near large chunks of metal at terminal velocity. Another possible hazard would come if the sport involves trying to hit an orbiting object from the ground in which case building let alone trying to wield a bow capable of launching an arrow out of the atmosphere would be dangerous,{{Citation needed}} illegal{{Citation needed}} and difficult. More casual versions could arise from playing on celestial bodies with less gravity and atmosphere but that would defeat the whole point.

Shooting an arrow aboard the ISS was considered in the ''what if?'' book.
|-
|🦉➡️📬
|Owlstuffing
|This appears to consist of attempting to stuff owls into mailboxes, which would be doubly illegal, because it would be cruel to the owls and interfere with the delivery of the mail. The mailbox is shown with the flag up, likely meaning that the point is to use these owls to attack mailmen, or that the point is to retrieve the owls from one mailbox and place them in another. Possibly a reference to owls carrying mail in the Harry Potter series.
|-
|🍴🕯️🍴
|Candle eating
|An even more unhealthy form of {{w|competitive eating}}. Eating large amounts of candle wax can cause {{w|Bowel_obstruction|intestinal obstruction}}.
|-
|⛳💣🏌️‍♀️
|Consequence golf
|The "consequence" of this game is simple: the bomb's eventual explosion necessitates efficient playing. Golfing with a bomb would likely significantly reduce the par on each hole, depending on the length of the fuse, and due to the threat of explosion, it would probably not be possible to exceed par unless the golfer is also very fast. There would certainly be damage to the course and golfers unless the holes extinguished the bombs of golfers who succeeded in time. The balance and rolling of the bomb balls would also be impeded by the fuses and caps. The bombs would also need to be very small to be used with standard golf clubs.
|-
|👉🐍👈
|Snake shaming
|Goal appears to be to humiliate a snake, although this may be impossible for most snakes due to their inability to understand humans.{{Citation needed}} Probably a play on snake charming. Also a possible reference to the biblical story where the snake is shamed for deceiving mankind by being doomed to crawl on its belly.
|-
|🔥🧗‍♀️🔥
|Hell escape
|Trying to escape the {{w|lake of fire}} is the pastime of damned souls, but perhaps living people are instead sent there and have to return home.
|-
|🎮🥑🎮
|Multiplayer avocado
|Unless a game based on avocados is the subject, there is, to say the least, a hardware compatibility issue here. Very different from the adult version, multiplayer eggplant (🎮🍆🎮; see [[1870: Emoji Movie Reviews]]).

3054: Scream Cipher

2025-08-17T08:09:37Z

2001:4450:813D:C800:3D62:5962:E748:B3F9: /* Trivia */

}}

==Explanation==
A {{w|Cipher}} is a method of encryption, where characters, or sometimes words, are substituted for other characters in a set pattern, allowing for arbitrary strings to be enciphered using it. The complexity and strength of ciphers varies, from {{w|one-time pads}} and (historically) {{w|enigma machine|Enigma}} as stronger and more complex, to {{w|substitution ciphers}} as some of the weakest and least complex, where each character is simply given a set different symbol to represent it in the cipher.

This comic uses a substitution cipher, where all the letters of the English Alphabet are represented using the letter "A", with different {{w|diacritical marks}} to define the differences. See details about the 25 marks in the [[#Trivia|Trivia section]] below. This kind of cipher is often used on a recreational basis by children or casual enthusiasts, the similarity of the letters increasing the obscurity of the content and the skill or technology required for use, but there is also significant impracticality, as not only are substitution ciphers the easiest to break, but also the similarities in the letters do make the cipher hard to read and easy to misread, and the detail in the diacritical marks makes it easy to draw the "A"s incorrectly or ambiguously, potentially leading to [[3003: Sandwich Helix|part of the message being lost]]. This was our experience in the comments section of this very article, where one person implemented translator functions alongside another person crafting a message that failed to translate. However, the logic behind the code is mostly visual similarity, and if attentive to connecting concepts between the Latin and scream cipher alphabet, it could be quickly learned and translated in a glance.

It's named "Scream Cipher" (as a pun on {{w|stream cipher}}s, commonly used in computing) because the written form of a scream is often a long string of As, possibly with some other characters at the beginning or the end (and often an exclamation point for emphasis), such as "Yyaaaaaww!” or “Aaaaaah!" or "Aaaaaaagh!". The name may or may not be a reference to IBM's {{w|Scream_(cipher)|Scream cipher}} published in 2002.

In the comic, [[Cueball]] texts the ciphered version for the plaintext "HELLO", and [[Megan]] responds with that for "HI". The title text deciphers to "AAAAAA A SCARY MONSTER AAAAAAA!", which would be a logical reason to actually scream. Another comic featuring all "A"s was [[2957: A Crossword Puzzle]]. Diacritics was also the main theme in [[1647: Diacritics]], was previously also mentioned in [[1209: Encoding]] and in [[1857: Emoji Movie]], where they have an important part of the pun, and is mentioned in one point of the list in [[1957: 2018 CVE List]].

===Worked example===
Say we want to encode "Scream" in the Scream Cipher. First we would need to split out word into the letters, so S, C, R, E, A, M. The first letter is S, so if we go to S in the table S is shown to become to Ã, C similarly becomes A̧, R becomes Ȃ, E corresponds to Á, A is the main letter so A is unchanged to A, and M becomes Ǎ. If we then write them again in order, we find SCREAM becomes ÃA̧ȂÁAǍ. To turn cipher text back into normal text, the process is repeated in reverse. To translate A̧ẢA̯A̰ÁȂ, we go to A̧ in the table and find A̧ becomes C. Ả similarly becomes I, A̯ becomes P, A̰ becomes H, Á becomes E, and Ȃ becomes R. If we write the letters in order, we see that A̧ẢA̯A̰ÁȂ becomes CIPHER.

Text can be automatically translated using any of the following community implimentations:
* The first known translator hosted on [https://github.com/Reginald-Gillespie/ScreamCipher GitHub Pages].
* A more bare-bones [https://github.com/matthewpwatkins/scream-cipher/ implementation] hosted on netlify.
* A terminal [https://github.com/klanderfri/ScreamCipher/ implementation].

==Transcript==
:[The top of the panel has the 26 letters of the alphabet written, each followed by a hyphen and the letter "A" with a unique diacritical mark for each. "A - A" is the only letter in the top row, and the only one where that A on the right side doesn't have a diacritic. The next 25 is sorted in a 5 by 5 grid, with the first five letters after A in the first column, then the next 5 in the second column and so on:]

Cueball and Megan is turned towards each other but with more separation than if they were engaged in normal discussion. They both look down at their phones not towards each other. The text they type is shown above their phone with a line starting in a starburst at the top of their phones going up the to the text.]

! Plain !! Unicode description !! Cipher !! Unicode description(s) !! Notes
|-
| A || U+0041 LATIN CAPITAL LETTER A || {{w|A}} || '''U+0041 LATIN CAPITAL LETTER A || Unadorned base character
|-
| B || U+0042 LATIN CAPITAL LETTER B || {{w|Ȧ}} || '''U+0226 LATIN CAPITAL LETTER A WITH {{w|Dot (diacritic)|DOT}} ABOVE || A with one dot over it, which can indicate a single change in math and science. Phonetic symbol for low central vowel.
|-
| C || U+0043 LATIN CAPITAL LETTER C || A̧ || U+0041 LATIN CAPITAL LETTER A, '''U+0327 {{w|Combining Diacritical Marks|COMBINING}} {{w|Cedilla|CEDILLA}}''' || Cedilla is often attached to a 'c', as in "français", as well as starting with 'c' itself. Appears similar to Ą (U+0104, A with ogonek) used in many language to denote a nasal a sound and in Polish to denote a nasal o sound; however, the two can be distinguished by the direction of the diacritic.
|-
| D || U+0044 LATIN CAPITAL LETTER D || A̱ || U+0041 LATIN CAPITAL LETTER A, '''U+0331 COMBINING MACRON BELOW''' || Some see the lower bar as similar to the lower edge of the D.
|-
| E || U+0045 LATIN CAPITAL LETTER E || {{w|Á}} || '''U+00C1 LATIN CAPITAL LETTER A WITH ACUTE || Many words have an acute e, as in "fiancé".
|-
| F || U+0046 LATIN CAPITAL LETTER F || A̮ || U+0041 LATIN CAPITAL LETTER A, '''U+032E COMBINING BREVE BELOW''' || The breve adds a second line to the A, much like how an F has two lines.
|-
| G || U+0047 LATIN CAPITAL LETTER G || A̋ || U+0041 LATIN CAPITAL LETTER A, '''U+030B COMBINING {{w|Double acute accent|DOUBLE ACUTE}} ACCENT''' || Adds two acutes to a letter.
|-
| H || U+0048 LATIN CAPITAL LETTER H || A̰ || U+0041 LATIN CAPITAL LETTER A, '''U+0330 COMBINING TILDE BELOW''' || The low tilde has horizontal ink in the middle that moves vertical toward the sides, like an H.
|-
| I || U+0049 LATIN CAPITAL LETTER I || {{w|Ả}} || '''U+1EA2 LATIN CAPITAL LETTER A WITH HOOK ABOVE || The hook almost looks like half of a circle, and the lowercase letter I (i) has a circular shape (known as a tittle) above it.
|-
| J || U+004A LATIN CAPITAL LETTER J || A̓ || U+0041 LATIN CAPITAL LETTER A, '''U+0313 COMBINING COMMA ABOVE''' || The comma symbol looks like a small letter 'J' in some fonts
|-
| K || U+004B LATIN CAPITAL LETTER K || Ạ || '''U+1EA0 LATIN CAPITAL LETTER A WITH DOT BELOW || 
|-
| L || U+004C LATIN CAPITAL LETTER L || {{w|Ă}} || '''U+0102 LATIN CAPITAL LETTER A WITH {{w|Breve|BREVE}} ||
|-
| M || U+004D LATIN CAPITAL LETTER M || Ǎ || '''U+01CD LATIN CAPITAL LETTER A WITH {{w|caron|CARON}} || The top-centered caron is the same shape as the top center of the M.
|-
| N || U+004E LATIN CAPITAL LETTER N || {{w|Â}} || '''U+00C2 LATIN CAPITAL LETTER A WITH CIRCUMFLEX || The lowercase letter 'n' also looks like a circumflex in some scripts. The circumflex peak mirrors the peak at the top left of the N.
|-
| O || U+004F LATIN CAPITAL LETTER O || {{w|Å}} || '''U+00C5 LATIN CAPITAL LETTER A WITH RING ABOVE || The symbol contains the letter 'O'. In Scandinavian languages like Swedish, this combination of 'O' and 'A' is a letter unto itself, mostly used in words where a long 'a' sound has acquired a more 'o'-like sound.
|-
| P || U+0050 LATIN CAPITAL LETTER P || A̯ || U+0041 LATIN CAPITAL LETTER A, '''U+032F COMBINING INVERTED BREVE BELOW''' || Refer to R: P also has a curve at the top center, but is encoded with one below.
|-
| Q || U+0051 LATIN CAPITAL LETTER Q || A̤ || U+0041 LATIN CAPITAL LETTER A, '''U+0324 COMBINING DIAERESIS BELOW''' || The two dots below the baseline reflect the two times Randall's Q touch the baseline. In the Orthographies of Spanish, Catalan, French and Galician, the grapheme 'qu' normally represents a single sound, before vowels 'e' and 'i'. In the few exceptions where the 'u' is pronounced, a diaeresis is added to it.
|-
| R || U+0052 LATIN CAPITAL LETTER R || Ȃ || '''U+0202 LATIN CAPITAL LETTER A WITH {{w|Inverted breve|INVERTED BREVE}} ||
The inverted centered top curve mirrors the curve at the top center of an R.
|-
| S || U+0053 LATIN CAPITAL LETTER S || {{w|Ã}} || '''U+00C3 LATIN CAPITAL LETTER A WITH TILDE || Tilde looks like a sideways 'S'.
|-
| T || U+0054 LATIN CAPITAL LETTER T || {{w|Ā}} || '''U+0100 LATIN CAPITAL LETTER A WITH {{w|Macron (diacritic)|MACRON}} || The macron looks like the top horizontal line in the letter 'T'
|-
| U || U+0055 LATIN CAPITAL LETTER U || {{w|Ä}} || '''U+00C4 LATIN CAPITAL LETTER A WITH DIAERESIS || The {{wiktionary|trema#Noun|two dot mark}} is used in many words in languages like German, Finnish and Swedish, with 'Ä' used as in "{{w|Die_Ärzte|Ärzte}}". As a true {{wiktionary|diaeresis#Usage notes|diaresis}}, it often indicates a vowel that is distinct from neighbouring vowels, rather than part of a {{w|Digraph (orthography)|digraph}} or longer phoneme. As a modifier of the vowel itself, as with the germanic/nordic languages, it is more properly called an 'umlaut' and may change a back vowel into a front vowel, though the two terms are often used interchangably.
|-
| V || U+0056 LATIN CAPITAL LETTER V || {{w|À}} || '''U+00C0 LATIN CAPITAL LETTER A WITH GRAVE || Grave has the letter 'V' in it, as well as being half of its shape.
|-
| W || U+0057 LATIN CAPITAL LETTER W || Ȁ || '''U+0200 LATIN CAPITAL LETTER A WITH {{w|Double grave accent|DOUBLE GRAVE}} || The letter 'W' is visually two copies of the letter 'V'
|-
| X || U+0058 LATIN CAPITAL LETTER X || A̽ || U+0041 LATIN CAPITAL LETTER A, '''U+033D COMBINING X ABOVE''' || The symbol contains the letter 'X'.
|-
| Y || U+0059 LATIN CAPITAL LETTER Y || A̦ || U+0041 LATIN CAPITAL LETTER A, '''U+0326 COMBINING COMMA BELOW''' || The comma mimics the vertical "tail" of the Y.
|-
| Z || U+005A LATIN CAPITAL LETTER Z || {{w|Saanich_dialect#Writing_system|Ⱥ}} || '''U+023A LATIN CAPITAL LETTER A WITH STROKE || The stroke through the letter A resembles the diagonal stroke of a capital "Z"
