{{incomplete|Created by an exciting BOT on the run - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic is a scatter plot comparing how exciting it is to see various things with how possible it is to chase those things using a convoy of coordinated vehicles.

The least chasable are stationary places like the {{w|Grand Canyon}} or {{w|International Date Line}}. It makes no sense to chase them because they don't move around, you just go to their known locations. At the other end of the chasability spectrum are animals that move around rapidly, and fleeting astronomical and atmospherical phenomena like {{w|clouds}}, {{w|meteors}}, and {{w|aurora}}. However, some of these are difficult to chase because they're small and hard to detect from a moving vehicle, e.g. {{w|gnats}}.

{| class="wikitable"
|-
! Entity || Explanation
|-
| {{w|Grand Canyon|The Grand Canyon}}|| Stationary place in Arizona. It's the largest canyon in the US (but not the world). It's very beautiful due to its depth and the color changes from different geological strata. So it's exciting to see and one of the most popular tourist attractions in the country.
|-
| {{w|Niagara Falls}} || Stationary place on the border of US and Canada, between the state of New York and the province of Ontario. The waterfall is the largest in North America by width and water volume, making it very beautiful to watch.
|-
| {{w|Tourist attractions}} || Other stationary places that attract many tourists (e.g. national parks, monuments, and historic places)
|-
| {{w|Tourist traps}} || Stationary places that market themselves as tourist attractions, but don't really have much to offer and exist mainly to sell food and souvenirs.
|-
| {{w|Sand trap}}s || Pits of sand in golf courses. If your golf ball lands in one, it's more difficult to hit it out to the grassy portions (fairways or greens), which is why it's a "trap".
|-
| The International Date Line || Jagged conceptual line running from the North to South poles around 180 degrees of longitude, used to separate the time zones that start and end each day. There's nothing to actually see at these locations, and it is intentionally mostly in oceans.
|-
| Meteors || Also called "shooting stars". These are fleeting streaks of light that are visible when bits of rock or dust enter the atmosphere and burn up. These are generally rare, making them exciting to see, but there are {{w|meteor showers}} when many are visible due to the Earth passing through a large cloud of dust (usually the remnants of a comet). To astronomy buffs, these can be like natural fireworks shows. Because each meteor streak lasts for a fraction of a second, it's not generally possible to chase them, although if the rock is large enough it may survive to the ground and become a {{w|meteorite}}, which chasers may be able to find by tracking its path through the sky.
|-
| {{w|Rainbows}} || A visual effect that occurs when sunlight is refracted by water droplets in the air, spreading the light into a spectrum of different colors. Rainbows are an optic phenomenon and have no physical "location", therefore it is impossible to actually reach them. In fact, "to chase rainbows" is an idiomatic expression that means "to pursue an unattainable goal".
|-
| {{w|Comets}} || Comets are chunks of rock and ice that orbit the sun, usually in highly eccentric orbits that take them from the inner Solar System to the {{w|Kuiper Belt}} or {{w|Oort Cloud}} at the extreme outskirts of the Solar System. Few of them are visible to the naked eye. They're exciting to see because they're rare, and one of the few astronomical objects that looks like more than just a tiny dot because there's a glowing "tail". While they're moving very rapidly through the Solar System, from the Earth they don't appear to move much faster than planets. So there's no need to chase them; when near the Earth, they will be visible from much of the planet for days or weeks.
|-
| {{w|Sunsets}} || Disappearance of the Sun below the horizon, should happen usually once every 24 hours (except close to the poles). Depending on weather conditions, they can sometimes be very pretty. Traveling around the Earth from east to west is needed for a continuous view of a sunset.
|-
| {{w|The Moon}} || Earth's only natural satellite with a predictable orbit. Only 12 people (the {{w|Apollo astronauts}}) have actually visited it in person; the rest of us see it from about 250,000 miles away. Weather permitting, it's visible for about half of every day/night cycle (though may be more obvious when this occurs significantly in the night sky, for several reasons). It doesn't move quickly in the sky, by apparent movement, so little chasing is necessary. A 'supermoon' is when the Moon looks the largest and shiniest, occurring when a full moon appears closest to the Earth in its orbit, though Randall doesn't consider this phenomenon impressive.
|-
| Unusual clouds ||
|-
| Regular clouds || Aerosol consisting of a visible mass of miniature liquid droplets
|-
| {{w|Fog}} || Atmospheric condition where water droplets are very dense near the Earth's surface, resulting in a visible haze. Very few people will chase fog.{{cn}}
|-
| {{w|Rain}} || Water droplets falling from clouds. In most of the world, this is a pretty common occurrence. Unless the volume is extremely high, there's rarely much excitement due to them, but extreme cases may cause flooding that can be dangerous. The only people who typically chase them are weather reporters.
|-
| {{w|Gnats}} || Hardly anybody wants to track down gnats, but people could theoretically use advanced instruments to do so.
|-
| Aurora || Impressive light displays that result from excitement of the Earth's {{w|magnetosphere}} by charged particles in the {{w|solar wind}}. These are generally only visible in high latitudes, so most people do not live where they're visible. Their visibility can be tracked and forecasted via monitoring of solar wind output from the sun, and particularly intense episodes can be predicted (as well as locations for viewing) on the basis of the solar cycle and solar flare activity. The release of this comic coincided with the strongest geomagnetic storm warning forecasted by the National Oceanographic and Atmospheric Administration (NOAA) in 20 years [https://www.swpc.noaa.gov/news/g4-watch-effect-may-11] ({{w|May 2024 solar storms}}).
|-
| Your favorite band's shows || Musical acts often plan tours, where they go around the country (or world) putting on shows every few days. Extreme fans with time on their hands may "chase" them by going to a series of their shows. Since the tour dates are planned and publicized well in advance, the shows are easy to find. However, depending on the popularity of your favorite band, this might be an expensive hobby, especially for optimal viewing.
|-
| Rare birds || Many birders will "twitch" to see rare birds, and this requires a fair amount of checking location, behavior, etc. Also, rare birds tend to be exciting to see.
|-
| Regular birds || These are easier to see than rare birds.{{citation needed}}
|-
| Regular balloons || Both children and adults accidentally let go of balloons, and may attempt to chase after them to retrieve them.
|-
| {{w|Tumbleweeds}} || A roughly spherical portion of certain plants that breaks off from its roots and rolls along the ground, propelled by winds. Most people don't find them very interesting to look at. They don't usually travel very quickly, so it would be possible to chase them if you were so inclined. (They may be of interest to plant biologists and ecologists.)
|-
| {{w|https://en.wikipedia.org/wiki/Speed_limit_enforcement|Speed traps}} || A section of a road where police often wait for passing drivers who are exceeding the speed limit, so they can catch them and issue speeding tickets. Frequent drivers, especially truck drivers, have developed systems to warn each other of these locations. ({{w|Citizens band radio}} was once the most popular method; now this can be done on mobile phones using services like {{w|Waze}}.)
|-
| {{w|Tornadoes}} || Wanting to witness a tornado is a typical objective of {{w|storm chaser}}s.
|-
| {{w|Whales}} || Widely distributed and diverse group of marine mammals.
|-
| {{w|Icebergs}} || Piece of freshwater ice broken off a glacier or ice shelf.
|-
| Hot air balloons || An aircraft whose bag is filled with heated air.
|-
| {{w|Radiosondes}} || Small instruments carried in weather balloons to gather and transmit atmospheric parameters. There's not much to see in them, but they're easy to track with a proper receiver.
|-
| Neighborhood possums || "Possum" is a common term for {{w|Virginia opossum}}s, the only species of opossum found in North America. In urban areas they will get into human garbage, and may carry diseases, so many may consider them pests and hunt them. A coordinate group of hunters can track them.
|-
| {{w|Ice cream trucks}} || Small vans that sell ice cream. They're easy to chase because they often play music and/or ring a loud bell so customers will know they're coming, and make frequent stops to allow customers to make purchases. Young "chasers" also often scream loudly when they hear the trucks coming, so others nearby (particularly parents or caregivers who are needed to provide the money) will be aware.
|-
| Other chasers || May result in an awkward encounter if met in person.

==Explanation==
{{incomplete|Created by a BLOOD FOR THE BLOOD GOD- Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This is a scatter plot comparing how good an idea sounds to how good the idea actually is. For example, leaded gasoline sounds like a good idea due to the anti-knocking effects, but is actually a bad idea due to lead toxicity. Fake prank fire extinguishers however sound bad and are bad as they can result in a dangerous situation in an emergency. Putting mold on infections sounds like a bad idea, but this could be referring to Penicillin, an antibiotic.

The title text combines leaded gasoline and a fake prank fire extinguisher into something that is worse than either. Not only is the fire extinguisher fake, it also releases flammable material onto the fire, and there is the additional lead toxicity.

{| class="wikitable"
|-
! Idea !! What it means !! How good it sounds !! How good it actually is !! Explanation
|-
|Leaded gasoline||Adding {{w|Tetraethyllead|tetraethyl lead}} as an antiknocking agent to allow for increased performance||++||---||Leaded gasoline was introduced in the early 1920s to allow higher pressures and temperatures in an engine without causing {{w|Engine_knocking|detonation (knocking)}}, allowing for increased fuel efficiency and engine performance; it also works to prevent engine valve wear. In essence, it artificially raises the {{w|octane rating}} of the fuel, reducing the need for refinement of the fuel, thus reducing waste and/or expense. Lead, however, is both toxic and bioaccumulative, meaning that lead released into the air over decades built up to harmful levels in people (as well as other animals) and almost certainly contributed to a host of health issues. Some scientists even suppose that {{w|Lead–crime hypothesis|crime level depends on lead exposure}}. (It should be noted that this only "[sounded] like a good idea" due to deliberate campaigns to obscure the known dangers).
|-
|Bloodletting||Releasing "bad blood" from the veins||---||---||You need (most of) your blood. Losing [https://www.ncbi.nlm.nih.gov/books/NBK542273/#:~:text=In%20a%20healthy%20adult%2C%20there,deviations%20in%20their%20vital%20signs. more than 15%] of a person's total blood volume results in adverse effects. Bloodletting has been performed as a medical procedure for at least 2000 years until the 19th century. The idea was to withdraw blood to balance the body's "humors". Despite this long history, the notion that bleeding someone is bad seems like basic common sense, and it's now well-understood that blood-letting (outside of certain rare and specific cases) does no good, causes significant harm, and quite certainly caused many deaths when it was used.
|-
|{{w|Asbestos}}||Mineral which does not burn, tolerates extremely high temperatures, and forms small fibers. These qualities make it excellent for insulation and fire protection||+++||---||Asbestos was used extensively in ships and buildings throughout most of the 20th century. Unfortulately, the microscopic fibers which make up asbestos greatly increase the risk of cancer when inhaled, causing its use to be banned in most countries.
|-
|Extension cords with prongs on both ends||allows easy connection between 2 female connectors||0 (neutral)||---||Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard, as seen in [https://www.youtube.com/watch?v=L08LjkN1k70 this Backyard Scientist video].
|-
|Stair kayaking||Riding down a flight of stairs in a {{w|kayak}}||--||---|| Stair kayaking is a stunt where a person positions a kayak at the top of a flight of stairs and then, using their paddle to push off, rides the kayak down the stairs (Example video showing kayaking down an escalator shown [https://youtu.be/46BjHAxgddU?t=154 here]). This poses significant easily foreseeable risks of injury or death, as well as being very bad for the kayak, which is designed to ride on [https://en.wikipedia.org/wiki/Kayak#:~:text=Modern%20kayaks%20serve%20diverse%20purposes,and%20long%2Ddistance%20ocean%20excursions. water], not stairs.
|-
|Fake prank fire extinguishers||||---||---|| The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds very dangerous and potentially life-threatening for many people, and it would, in fact, be highly dangerous. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. An example of a similar situation, although not intended as a prank, can be found [https://twitter.com/ThatSamWinkler/status/1657154071051239424 here].
The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.
|-
|Always saying what you think||...regardless of the feelings of others or other considerations||++||--||Openness and honesty are seen as positive character traits in people. However, taken to the extreme of ''always'' telling people what you think about them, they can lead to awkward or unpleasant situations. It may harm your relationship with the other person if they don't like what you think, or they may reply without concern for ''your'' feelings or other considerations. Keeping negative thoughts to yourself or telling "white lies" can be considered a better alternative in some situations.
|-
|Replying to spammers||Clicking on the "Reply" button from spam mails and writing (and sending) a reply (or worse, clicking on the links in these mails)||--||--||At best, you confirm your email address and identify yourself as someone likely to respond to such unsolicited messages, and so encourage the spammers to deluge you with even more messages. At worst, the spammer may use your correspondence to extract sensitive information about you, or make you victim to a scam.
|-
|Solar cars||Having {{w|Solar panel|solar panels}} on the car's surface (mostly hood and roof) for power generation||+++||-||Powering electric vehicles with solar panels seems like an excellent idea: it would provide free power with no increased land use, and theoretically could allow a vehicle to operate indefinitely without being fueled or charged. However, such vehicles couldn't operate without batteries (due to power requirements, weather and shade conditions, and nighttime driving), so they'd have increased complexity compared to plug-in or hybrid cars. Adding solar panels would add cost, weight, manufacturing complexity, and maintenance requirements. Solar panels on moving cars are less efficient than in stationary installations, and subject to damage from both collisions and road debris. Solar cars do exist (the {{w|World Solar Challenge}} is a competition for such cars), but as a practical form of transportation, the negatives likely outweigh the positives.
|-
|Heelies||{{w|Heelys}} are shoes with a inline skate wheel embedded in the sole, at the heel. ||+||-||Heelys allow the wearer (usually children) to shift between normal walking and rolling like a roller skate. This sounds like fun but has led to numerous injuries.<ref>Childs, Dan (2009-02-10) [2007-06-04]. [https://web.archive.org/web/20221001021115/https://abcnews.go.com/Health/Exercise/story?id=3242181&page=1 "Heelys Hazardous for Kids, Study Finds"]. ''ABC News Medical Unit''. Archived from [https://abcnews.go.com/Health/Exercise/story?id=3242181&page=1 the original] on 2022-10-01. Retrieved 2024-05-07.</ref>
|-
|Prequels||A work of fiction (mostly movie) telling the "story before the story" of another work of fiction.||+++||-||More of a good story sounds great on the surface, and audiences who are invested in a set of characters and/or a setting often love the idea of finding out what led up to certain events. But there are a number of pitfalls. Any spin-off of a popular property risks becoming a low-quality cash grab. Prequels, specifically, are constrained by the fact that they have to lead to the story that's already been released, which can lead to contrived storytelling. There's less room for suspense, since the future of the storyline has already been established. There's a tendency to invent or fill in detailed backstories, which can undermine character arcs, and/or destroy the mystery and nuance of certain characters. It's not impossible for prequels to be good, of course, but there are a lot of ways they can go wrong.
|-
|Transitions® lenses||A brand name for {{w|Photochromic_lens|photochromic lenses}} in glasses, which get darker (like sunglasses) in bright light.||+||-||Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the exposure is removed. The advantage is that wearers of glasses don't need to buy separate (prescription) sunglasses. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, perhaps in a forest or when driving. Also, car windscreen filter out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark and in cold weather they might stay dark for too long.
|-
|Cutting pizza in squares||Cutting (a presumably round) pizza in squares||-||-||Most people cut pizza into wedges and hold it by the crust. Cutting it into squares allows for more pieces to be shared, but pieces near the center will have no crust to hold it by, getting cheese and sauce all over your fingers. There will also be lots of leftover tiny pieces. While hardly a disaster like the other items in its quadrant, square pizza pieces are just not very useful and rather inefficient. Cutting a rectangular pizza into squares might not suffer from the problems above, but, unless the pizza itself is square and cut only into four squares, some people will end up with a higher crust-to-topping ratio than others. Cutting a round pizza into squares is popular in Chicago and is sometimes called tavern-style or party-cut and some<sup><nowiki>[</nowiki>''{{w|Wikipedia:Manual_of_Style/Words_to_watch#Unsupported_attributions|who?}}''<nowiki>]</nowiki></sup> consider it the real Chicago style pizza rather than deep dish pizza<sup><nowiki>[</nowiki>''{{w|Wikipedia:Accuracy_dispute#Disputed_statement|dubious}}''<nowiki>]</nowiki></sup>.
|-
|{{w|Project Orion (nuclear propulsion)|Project Orion}}||Study by the U.S. government looking into nuclear pulse propulsion for spacecraft.||---||-||Using repeated nuclear explosions to generate motion sounds bad for both the spacecraft and everything else, especially with a ground launch, but there are ways to address a lot of the concerns, so it isn't as bad as it sounds. Project Orion's theorized specific impulse and thrust would also be far higher than anything chemical rockets can accomplish. The efficiency of Project Orion is extremely low, however, and the {{w|ablation}} issues are extremely difficult to overcome.

See also [[2423:_Project_Orion | comic 2423: Project Orion]].
|-
|Soup||{{w|Soup}}||0 (neutral)||0 (neutral)||Soup is probably one of the oldest foods created by prehistoric cooks. Many people enjoy it, though some consider many soups somewhat lacking as a meal on their own, or boring.
|-
|Combo washer dryers||A device which combines washing machine and laundry dryer into one device||+++||+||Better at space efficiency, but worse at each task than separate devices.
|-
|Cutting sandwiches diagonally||Cutting sandwiches diagonally||+||+||[https://www.popularmechanics.com/science/math/a32690399/triangles-rectangles-best-way-cut-sandwich-math/ Generally] [https://www.npr.org/2009/11/28/120914097/rectangles-vs-triangles-the-great-sandwich-debate regarded] as the superior way to slice a sandwich, providing more aesthetically pleasing display of the contents, better support in the hand and fewer all-crust bites. Required in the assembly of a club sandwich,{{actual citation needed}} where the diagonal components are stacked again.
|-
|{{w|Diverging diamond interchange}}s||Road junction where the two (sets of) lanes cross over to switch sides (so if you normally drive on the right, now you drive on the left), then switch back to normal after the junction||-||+||Highway engineers believe the shape improves safety and traffic flow through the interchange because switching to the other side facilitates merging to and from the other road in the junction. However the shape appears to be insanity to an unfamiliar driver.
|-
|Toasting sandwiches||Making a sandwich first and then cooking it, as in a dedicated {{w|Pie_iron|sandwich toaster}}, a {{w|toaster oven|toaster oven}} or frying pan, or under a grill.||++||++||The grilled cheese sandwich is a familiar form to most people, and many other sandwiches are improved by toasting as a final step. Others, such as the {{w|western sandwich|Western}} or {{w|club sandwich|club}} are prepared using toast. The {{w|peanut butter, banana and bacon sandwich|Elvis}} is a specific case of a sandwich that normally wouldn't be toasted, but is improved by it - peanut butter, bacon, banana, and jelly, with the assembly lightly fried.
|-
|Crumple zones||Designated areas of a car that crumple in case of a crash. ||--||++||Most peoples' intuition would be that stronger cars are safer, and intending parts of a vehicle to collapse ''by design'' might seem crazy. But engineered crumple zones are designed to absorb the kinetic energy in a vehicle collision, and do so in such a way as to protect the passenger cabin. This significantly reduces the danger of injury or death from crashes.
|-
|Sliced bread||Bread, sliced by the baker before packaging for sale||+++||++||It's far more convenient for making sandwiches or toast, but unfortunately pre-sliced bread will go stale faster and some applications may be better off thicker or thinner than the slices provided. Sliced bread is often used as a comparator for how good something is in the phrase 'the best thing since sliced bread'.
|-
|Pizza||{{w|Pizza}}||++||++||Pizza is a widely popular dish throughout much of the world, uncontroversial {{w|Anchovies_as_food|except}} {{w|Pineapple|certain}} [https://www.taste.com.au/recipes/nutty-choc-pizza-fresh-berries/2c0220a4-8463-45ff-b2ba-ac7e5012a006 toppings].
|-
|Eating citrus fruit while at sea||Having a supply of {{w|citrus fruit}} on long sea journeys, especially during the {{w|Age of Sail}} ||0 (neutral)||+++||For a long time, {{w|Scurvy|scurvy}} was a serious danger to sailors, who generally subsisted on a monotonous diet with low vitamin content while on ships. Most citrus fruits are rich in vitamin C, which prevents scurvy. Eating orange or lemons doesn't seem like a significant activity one way or the other, but it's an easy way to prevent a disease that causes serious ill-health and possibly a painful death.
|-
|Putting mold on infections||Seemingly a reference to ancient practice of pressing moldy bread against infected wounds||---||++||While this sounds like a good way to get a fungal infection, with the correct mold this is a primitive antibiotic, and led to the discovery of {{w|penicillin}}.
|-
|Wheels on luggage||Some luggage bags have small wheels inset on their frame and a carrying handle.||+++||+++||A relatively simple fitting for rigid or semi-rigid luggage that substantially eases its transport over long distances on flat surfaces such as travel terminals.
|-
|{{w|Heat pump}}s||Refrigeration (or air conditioning) technology operated in reverse to heat an area instead.||++||+++||Heat pumps use refrigeration cycles to warm a space or mass, but aren't designed to generate heat. Instead, they extract thermal energy from the surrounding environment. This allows a space to be heated with significantly less energy use than a furnace or resistance heater. Because these units are operated by electricity, they can provide heating with renewable energy (potentially using {{w|thermal energy storage}} for load-shifting), they reduce or eliminate the need for natural gas connections, and prevent a number of risks that come with traditional furnaces (such a carbon monoxide leaks and fires). In addition, heat pumps use the same refrigeration cycles as air conditioners, so a single unit can be designed to both heat and cool a building. It sounds like a good idea, and works out pretty well in real life.
|-
|Laser eye surgery||Surgical techniques using lasers for precision cutting in the eyeball.||-||+++||In the popular imagination, lasers are often thought of as something used for destroying their target. Firing them into people's eyes, then, does not sound a great idea. However. this technology has substantially improved the eyesight of millions of people worldwide by allowing treatment of eye problems otherwise only corrected by lenses, or entirely untreatable. Randall has previously commented on laser eye surgery, amongst other ideas both good and bad, in [[1681: Laser Products]].
|-
|Fecal transplants||Transfer of gut microbiome of healthy person to sterilised gut of ill person.||---||+++||The gut microbiome is a collection of bacteria that lives in our guts. It can influence our health. It is responsible for last stages of digesting our food. It can also produce neurotransmitters that are carried by blood to our brain influencing our behaviour. A healthy microbiome can be destroyed by bad eating habits, unhealthy lifestyle, infections or antibiotics. The important part is a composition of different species of bacteria that compromise the biome. Sometimes it may be necessary to completely sterilise the gut and then take a sample of a healthy biome from another person. A sample is enough as the bacteria will multiply. As long as the patient eats correctly, the microbiome after transplant should develop correctly.

It sounds bad because we tend to think of our feces as something gross, to be discarded. It is called fecal transplant as our feces contain about 50% of gut bacteria, but nowadays the sample usually takes the form of a coated pill that is applied rectally.

In this comic, [[Cueball]] finds his game of chess against [[Megan]] to be too difficult, and he attempts to tap his subconscious to find his next move. This is a common technique used in more physical competitions like baseball or golf, where overthinking can interfere with one's motion and thus "clearing one's mind" and relying on the subconscious is useful to overcome such mental barriers. However, chess is more a game of planning and strategy than natural movement, and the rules of chess are not ingrained into Cueball's subconscious, and so his subconscious ends up feeding him invalid moves and beginner questions concerning movement rules.

{{w|Chess}} is a board game in which two players take turns to move a variety of different pieces representing units on a battlefield to try to checkmate the other player's king. Chess has a lively tournament scene, and it takes much practice to attain a competent level of skill in the game. Different pieces can move and capture in different ways; pawns can only move forward by one square unless it's their first move, in which case they can move up two squares. They can only capture by moving diagonally, including when capturing ''{{w|En passant|en passant}}'', in which case they move behind an opposing pawn that had moved forward two squares on the previous turn. Other pieces have different rules.

{{w|Obi-Wan Kenobi}} is a character from the movie series ''{{w|Star Wars}}'' who played the mentor figure to the protagonist, {{w|Luke Skywalker}}. One of his pieces of advice to his mentee was to relax and listen to his subconscious in strenuous times. However, Obi-Wan gave this advice because Luke was connected to The Force, a mystical energy in the ''Star Wars'' universe that connects to the entire universe; not being a part of the ''Star Wars'' universe, Cueball is unable to tap into it. The Force does have similarities to real-life concepts used in various Eastern philosophies, but they are not typically used to play chess, for the same reasons given above.

The title text refers to a scene in the chess movie ''{{w|Searching for Bobby Fischer}}'', in which Sir Ben Kingsley's character dramatically sweeps the pieces off the board and instructs his student to see the pieces in his mind, which the child proceeds to do. Randall considers this impractical, presumably for similar reasons as the Obi-Wan example.

:[Cueball and Megan are playing chess; Cueball is leaning forward over the chessboard.]
:Cueball (thinking): Why is chess so hard? Maybe the answers lie within me. Maybe I just need to let go, relax, and let my instincts and subconscious speak.

:[Cueball leans back and places his hands to his head.]
:''Meditate''

:Cueball's subconscious: Knight to G-4

:[Beat panel.]

:Cueball: That's not even a legal move.
:Cueball's subconscious: Okay, hold on. How do the pawns capture, again?
:Cueball: Man, Obi-Wan was full of crap.
