&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 862&lt;br /&gt;
| date      = February 18, 2011&lt;br /&gt;

| image     = let go.png&lt;br /&gt;
| titletext = After years of trying various methods, I broke this habit by pitting my impatience against my laziness. I decoupled the action and the neurological reward by setting up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
It is human nature to lose interest in difficult or boring tasks, and instead do something easier, more interesting or more rewarding in the short term. While procrastination and distraction from more important tasks has always been present, this comic casts a light on the internet and the huge potential for distraction which it provides. &lt;br /&gt;
&lt;br /&gt;
The first two frames in this comic are the set-up, and contain the websites {{w|CNN}} and {{w|Reddit}} and thoughts over the top of them. These types of websites that are regularly updated with new content are prime candidates for distraction. The thought bubbles indicate that the reader is fully aware that they shouldn't be looking at these websites, but is unable to stop himself. Even the very rational thought that checking news stories more than once a day is bordering on pointless doesn't seem to stop him.&lt;br /&gt;
&lt;br /&gt;
In the third frame, it starts to look a little different as the screen is not a computer but is in fact the targeting computer from {{w|Luke Skywalker|Luke Skywalker's}} {{w|X-wing}}. At this point it becomes clear that there are ''far'' more important tasks at hand, namely flying the craft. Even then, Luke has an internal conflict and considers checking {{w|Facebook}}, but mentally checks himself, and to prevent himself from further compulsive browsing shuts down the system. The thought bubble at the bottom is one that is probably familiar to many people (especially students), where he realizes that he has to turn off the computer to actually concentrate on the important task.&lt;br /&gt;
&lt;br /&gt;
In the fourth frame, we finally get the movie reference from {{w|Star Wars}} as {{w|Princess Leia}} and one of the Rebel Alliance's officers are gathered around the holographic table that allows them to follow the battle. In the movie, Luke turns off his targeting computer because he uses the [http://en.wikipedia.org/wiki/The_Force_%28Star_Wars%29 force] to fire the torpedoes at the right time. But in this comic, Luke turns off the computer because he keeps getting distracted by Reddit and CNN. When they ask whether he is alright, he responds in the way most people would who have nearly been caught wasting time on the internet. This is however a quote of what he actually replies in the movie. &lt;br /&gt;
&lt;br /&gt;
See the [http://youtu.be/DOFgFAcGHQc Destruction of Death Star] scene on YouTube. The ''Let Go'' remark from {{w|Obi-Wan Kenobi}} that had given the title to this comic occurs about [http://youtu.be/DOFgFAcGHQc?t=2m two minutes into the clip]. Though here it is a reference to let go of refreshing websites...&lt;br /&gt;
&lt;br /&gt;
The headlines on CNN read 'Bees?', 'Where is {{w|Oman}}?', and 'iReport (we mean you, that is.)'.&lt;br /&gt;
&lt;br /&gt;
The headline ''Bees?'' cannot be a reference to {{w|Cards Against Humanity}} because it came out a few months after this comic. It probably is just a question to the picture above - if it was bees following the guy.&lt;br /&gt;
&lt;br /&gt;
The headline ''Where is Oman?'' is below a map where land is white. It shows Cyprus, Northern Egypt and the Middle East with the Mediterranean Sea, the Red Sea and the Persian Gulf (seas are grey). Oman is not on this map as it is not situated on the Persian Gulf; it's on the Gulf of Oman and on the Arabian Sea, both of which can be considered parts of the Indian Ocean.&lt;br /&gt;
&lt;br /&gt;
The title text is a serious solution to a procrastination problem that we see in the comic, [http://blog.xkcd.com/2011/02/18/distraction-affliction-correction-extensio/ later explained] to take the form of simply rebooting the computer.  Randall just used the honor system, rather than enforcing this behavior with a program, but he solicited suggestions from his commenters for browser addons, for people who could not simply reboot their computers for whatever reason.  At the time, a commenter suggested DelaySites, but that addon is no longer available; nowadays, Mozilla recommends [https://addons.mozilla.org/en-US/firefox/addon/leechblock-ng/?src=search LeechBlock NG] (also [https://chrome.google.com/webstore/detail/leechblock-ng/blaaajhemilngeeffpbfkdjjoefldkok?hl=en-US available for Chrome]), which can be configured to implement the loading delay or block websites entirely, with additional parameters for adjusting time limits for browsing and the time of day and days of the week that each behavior is active. [https://one-sec.app/ One Sec] is another option with mobile support and some extra features. &lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1544&lt;br /&gt;
| date      = June 29, 2015&lt;br /&gt;

| titletext = Otherwise known as Margaret the Destroyer, I will bring pain to the the Great One. Then again, maybe I won't.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic uses the starting lines of an innocent children's book and creates irony by delivering a dark message.&lt;br /&gt;
&lt;br /&gt;
In the book ''{{w|Are You There God? It's Me, Margaret.}}'' by {{w|Judy Blume}}, the opening lines are &amp;quot;Are you still there, God? It's me, Margaret. I know you're there, God. I know you wouldn't have missed this for anything! Thank you, God. Thanks an awful lot...&amp;quot; These lines describe a prayer, in which Margaret privately speaks to God, expressing gratitude and seeking guidance.&lt;br /&gt;
&lt;br /&gt;
In the second and third panels, Margaret asks God &amp;quot;Are you scared, God?&amp;quot;, and states &amp;quot;You should be&amp;quot;. This is similar to threats delivered in some action movies, such as Taken, in which the protagonist or antagonist speaks directly to their opponent, issuing threats and indicating that they are coming after their opponent. The final panel is a shot of Margaret standing imposingly in a dark landscape, and a caption over the top of the image says &amp;quot;Margaret is coming for you&amp;quot;, making this comic reminiscent of an action movie trailer. The irony is that &amp;quot;Are You There, God? It's Me, Margaret.&amp;quot; is a very innocent book, especially when compared to this type of action movie.&lt;br /&gt;
&lt;br /&gt;
The title text is a mashup of three of Blume's other books: ''{{w|Otherwise Known as Sheila the Great}}'', ''{{w|The Pain and the Great One}}'', and ''{{w|Then Again, Maybe I Won't}}'', and likely the inspiration for the dark lines in the comic.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Margaret, shown in full body, is alone. She is talking while looking out towards the reader.]&lt;br /&gt;
:Margaret: Are you there, God? It's me, Margaret.&lt;br /&gt;
:Margaret: I know you're listening.&lt;br /&gt;
&lt;br /&gt;
:[Zoom in on her face and torso.]&lt;br /&gt;
:Margaret: Are you scared, God?&lt;br /&gt;
:Margaret: Are you?&lt;br /&gt;
&lt;br /&gt;
:[Zooming so far in that not even her whole face is visible.]&lt;br /&gt;
:Margaret: You should be.&lt;br /&gt;
&lt;br /&gt;
:[Zooming far out showing her in a white silhouette against a black sky, standing on the white earth.]&lt;br /&gt;
:Margaret: ''Margaret is coming for you''.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*There seems to be a typo in the title text with double the:&lt;br /&gt;
**''I will bring pain to '''the the''' Great One''.&lt;br /&gt;
**It could however also be a reference to the book ''The Pain and the Great One'', so this is the &amp;quot;The Great One&amp;quot;.&lt;br /&gt;
**Maybe it was supposed to be &amp;quot;thee, The Great One&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
*There doesn't seem to be a typo if you pause after the first the. '''thee the''' would have been better. Realizing that God is &amp;quot;the Great One&amp;quot; may be the reason for the last part of the title text (Then again, maybe I won't.)&lt;br /&gt;
*I know you're listening&amp;quot; may refer to an earlier xkcd comic, [[525: I Know You're Listening]].&lt;br /&gt;
*The idea of turning an innocent children's book into a violent movie was previously touched in [[633: Blockbuster Mining]].&lt;br /&gt;
*Are You There, God? It's Me, Margaret was previously referenced in the title text of [[1354: Heartbleed Explanation]].&lt;br /&gt;

:True, but the reason the sought after person is presumed to be a woman is because it is implied that Cueball is motivated by love and xkcd's typical depiction of romantic love is heterosexual. It is, of course, certainly possible that the person sought after is loved in a non-romantic sense, but romantic love seemed most plausible to me. This was the reason for the sentence &amp;quot;It is not explicitly made clear whether the loved one in question is a woman with whom he is in love, a family member, or a relation of some other kind, but presumably the loved one is either his girlfriend or wife.&amp;quot; The use of &amp;quot;she&amp;quot; throughout the rest of the explanation was done from this perspective.

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
On statistical charts and graphs, it is common to include {{w|error bars}} showing the probable variation of the actual value from the value shown (or the possible error of the value shown). Since there is always uncertainty in any given measurement, the error bars help an observer evaluate how accurate the data shown is, or the implications if the true value is within the likely error, rather than the exact value shown. There are statistical methods for calculating error bars (they can show a {{w|standard deviation}}, a {{w|standard error}}, or a {{w|confidence interval}}) but the fact that there are multiple ways of calculating them - plus general unfamiliarity with statistical methods - means that people often misinterpret or misunderstand them.&lt;br /&gt;
&lt;br /&gt;
As charts may be of data that has been mathematically processed, the known error from the recording process must also be mathematically processed in order to determine the likely error in the final result - a process called propagation of error. Different transformations of the data result in different transformations of the error, and the correctness of the transformations used can sometimes depend on the subtle differences in the distribution of the source data. At a loss as to how to correctly propagate all the possible sources of error, [[Randall]] instead puts error bars on the ends of his error bars to reflect his uncertainty in the original error bars. However, since his second error bar calculations are also suspect, he puts a third set of error bars on them.  This repeats {{w|ad infinitum}} (though only four levels are drawn), creating a fractal-like object.&lt;br /&gt;
&lt;br /&gt;
In the title text, he says that the {{w|effect size}} of some variable being calculated is 1.68 and follows it with a 95% confidence interval, or CI (a range of possible values which, under repeated sampling, would contain a number within the interval 95% of the time), which would normally be represented by something like &amp;quot;1.68 (95% CI 1.56 - 1.80).&amp;quot; Since he is stating that those bounds are uncertain, he starts with &amp;quot;1.68 (95% CI 1.56&amp;quot; but then puts the 95% CI for that lower bound of the interval, &amp;quot;95% CI 1.52,&amp;quot; followed by the lower bound for that value, &amp;quot;95% CI 1.504,&amp;quot; and so on. He goes 11 layers deep before resorting to an ellipsis.&lt;br /&gt;
&lt;br /&gt;
In real life, there is not enough data to compute an error bar on error bars. The data being measured have a sampling distribution, e.g. one might make ten measurements of something which come out to 1, 1, 1.1, 1, 1.4, 1, 1, 0.5, 1, and 1, suggesting it is probably close to 1, so there is a range of values that could likely be. However, properties such as the average and standard deviation do not themselves typically have ranges. If one is uncertain that one has computed these correctly, there is not enough data to compute one's own uncertainty in one's skills in any meaningful way; one can claim error bars on error bars, as in this example, but those are just guesses with no statistically useful backing. One way to make the nested error bars valid might be (if one had the time and money) to run the entire experiment ten times, calculating sigmas each time; then there would be a valid (although not necessarily useful) sigma on the sigmas. Then one would have to run the set of ten runs ten times for the next &amp;quot;level&amp;quot; of sigmas, etc. The difficulty of doing this entire process, especially when considering that Randall is only nesting error bars out of ignorance, makes this comic all the more absurd.&lt;br /&gt;

:[A line graph with eight marks on the Y-axis and five marks on the X-axis.  The graph has four points represented by dots and connected by three lines between them.  Each dot has error bars coming out of the top and bottom of it.  The horizontal line delineating the end of each error bar has another set of smaller error bars attached to it.  These second error bars in turn have a still smaller third set of error bars attached to the end of them.  There is a final fourth set of very small error bars attached to the third set, for a total of 56 error bars]&lt;br /&gt;

&lt;div&gt;{{comic&lt;br /&gt;
| number    = 827&lt;br /&gt;
| date      = November 29, 2010&lt;br /&gt;

| titletext = We didn't believe you at first, but we asked like three people who were at that party. They not only corroborated your story, but even said you totally mentioned wanting to start a company someday. Sorry! If this isn't enough money, let us know.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
Many people have shared [[Cueball]]'s experience of seeing someone else make a profit from an idea that they themselves had. This comic plays with the thought of what would happen if {{w|intellectual property}} thinking was taken to an extreme, and if companies or people were keener on &amp;quot;setting things right&amp;quot; than money. The title text is an extension of the comic with increasingly extreme thinking.&lt;br /&gt;
&lt;br /&gt;
In reality, having a great idea alone, of course, does not create a profitable business; there must generally be an enormous amount of work and effort (not to mention risk-taking) put in to create a business from scratch, popularize it, and keep it standing. Cueball, having done none of this, would probably not deserve close to the &amp;quot;30% cut&amp;quot; he claims even if intellectual property did work the way it is presented here.&lt;br /&gt;
&lt;br /&gt;
This comic originally was shared with name [[1721: Business Idea]], but then this comic was renamed. There were no other relations between the ideas for the two comics, see the trivia section below.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;

&lt;br /&gt;
==Trivia==&lt;br /&gt;
*This comic was originally called &amp;quot;Business Idea&amp;quot; but Randall renamed it to fix a conflict on xkcd when he released [[1721: Business Idea]] about five years later (as in the comic).&lt;br /&gt;
**This comic was thus also renamed on this page.&lt;br /&gt;
**It gave quite some turbulence on the release day as can be seen in the [[1721: Business Idea#Trivia|trivia section]] of the new comic.&lt;br /&gt;
*The delivery address is to Ash Tree Lane, and as shown in [[472: House of Pancakes]], Randall knows how to mess with people who've read House of Leaves.&lt;br /&gt;
*20,000,000$ x 30% = 6,000,000$- a lot of cash for doing nothing but having an idea.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 861&lt;br /&gt;
| date      = February 16, 2011&lt;br /&gt;
| title     = Wisdom Teeth&lt;br /&gt;
| image     = wisdom_teeth.png&lt;br /&gt;
| titletext = I heard the general anesthesia drugs can cause amnesia, so when I woke up mid-extraction I started taking notes on my hand so I'd remember things later. I managed 'AWAKE BUT EVERYTHING OK' before the dental assistant managed to find and confiscate all my pens.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
{{w|Wisdom teeth}}, as many people are no doubt {{w|Wisdom teeth#Post-extraction problems|painfully aware}}, are the third set of molars found in humans. Because human jaws are smaller than other ape jaws, most of us don't have room for a third set of molars, and the teeth become impacted so they grow straight into the other teeth, requiring a painful, debilitating procedure to remove them.&lt;br /&gt;
&lt;br /&gt;
Because recovering from dental surgery often entails a period of rest following the operation and the use of {{w|painkillers|prescription painkillers}} (which have a tendency to make a person go a little loopy), [[Cueball]] prepares to play ''Minecraft'' the entire time. ''{{w|Minecraft}}'' is a PC game known for its addictive qualities; the game itself primarily revolves around a three-dimensional world in which the goal of the player is centered on the aspects of structural creation using blocks found in the environment and the creation of different materials for use in building these structures. Despite its addictive nature, the game doesn't provide the player with a goal, so most people take to building lots of nifty stuff, such as large cities, computers made from the game's built-in automation mechanics, massive scale replicas of Earth, etc.&lt;br /&gt;
&lt;br /&gt;
Cueball's conversation with [[Megan]] indicates that he has previously decided against playing ''Minecraft'' precisely due to its addictive gameplay and lack of internal goal, deeming it unproductive. However, 'productivity' is not something that Cueball believes he can achieve post-extraction, and so Cueball decides that addictive gameplay and lack of internal goal &amp;quot;sounds like the perfect distraction&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Unfortunately for Megan (and any other users of her server), Cueball, while intoxicated with painkillers, has instead opted to flatten an entire continent and sort it into layers (by type of block, presumably). While there's no real indication of how big the continent is, as ''Minecraft'' worlds are randomly generated, sea level in ''Minecraft'' is at Y level 64, which means he sorted at least 65 layers of a continent large enough to be sufficiently developed, so it is clear that this task would take a lot of time. Collecting a block in ''Minecraft'' takes a certain minimum amount of time, depending on the block type, so even if he did everything as fast as he possibly could, there's still a substantial lower bound.&lt;br /&gt;
&lt;br /&gt;
Ironically, in the second panel Megan says she'll set Cueball up on her server, which indicates she probably uses a whitelist to secure the server from griefers who might destroy structures created by others, not expecting that Cueball would do exactly that. The last panel simply illustrates that painkillers tend to make one loopy.&lt;br /&gt;
&lt;br /&gt;
The title text refers to people waking up during surgery. Because anesthesia requires a lot of careful calibration and dosage - there's a reason anesthesiologists are paid hundreds of dollars an hour to be there, after all - it's possible to sometimes get it wrong, resulting in the patient waking up in the middle of the surgery. The three most important parts of anesthetics used for surgery are an analgesic (blocks pain), a sedative (puts you to sleep), and a paralytic (keeps you from moving). The worst-case scenario that most people hear about is when the analgesic and sedative are under-dosed, but the paralytic is correct, leaving the person awake, able to feel pain, but unable to alert the surgeons that anything is wrong. As a result, some countries and medical institutions have passed laws requiring surgeons to monitor brain activity so that these problems can be quickly remedied. The situation the title text is describing, with both the sedative and paralytic wearing out (leaving the person able to write notes), would be quite unlikely. As for confiscating all the pens, it was probably just to keep the patient from disturbing the procedure while the anesthesiologist corrected the dosage.&lt;br /&gt;
&lt;br /&gt;
In reality, sorting a ''Minecraft'' map into layers (assuming the grass in the comic is at sea level—y=64 blocks) would take an unbelievable amount of time, even in creative mode, as you would have to mine away everything below that, and then sort it into layers. ''Minecraft'' maps are extremely big, so it would actually be almost impossible to sort the entire map into layers. Randall, like Cueball, has also tried to do weird things with ''Minecraft'', see [https://what-if.xkcd.com/153/ this] for more details.&lt;br /&gt;
&lt;br /&gt;
In the current version of Minecraft: there is a way to create a world flattened with the option superflat world. However, this option was not avaliable at the time the comic was published, so Cueball really flattened an entire world himself. Also, in the current version, by standard, worlds are almost infinite, again, this was not avaliable at the time.&lt;br /&gt;
==Transcript==&lt;br /&gt;
:Cueball, on phone: Hey! Know how you've been bugging me to play Minecraft for the past year? I'm game.&lt;br /&gt;
:Megan, on phone: But you said you didn't want to &amp;quot;get hooked and spend days on end moving virtual cubes around while sitting motionless.&amp;quot; What changed?&lt;br /&gt;
&lt;br /&gt;
:Cueball, on phone: I'm having my wisdom teeth out, and I'll be useless and doped up on painkillers for the next few days, so that actually sounds like the perfect distraction.&lt;br /&gt;
:Megan, on phone: Oh. I'll set you up on our server!&lt;br /&gt;
&lt;br /&gt;
:72 hours later...&lt;br /&gt;
:[Megan sitting at computer.]&lt;br /&gt;
:Megan, on phone: Hey — starting to feel better? Enjoying the game? Let's see what you've... What the hell? Where ''IS'' everything?&lt;br /&gt;
&lt;br /&gt;
:[View of a Minecraft screen showing a vast empty expanse of land. In Cueball's hotbar is, from left to right, an stone pickaxe, sword, and shovel, seven feathers, 42 torches, a non-enchanted bow, a blank space, 64 blocks of stone and a clock. He has full health and 15 armor points.]&lt;br /&gt;
:Megan, offscreen: ...You made the entire continent perfectly flat?&lt;br /&gt;
:Cueball, offscreen: And sorted it into layers.&lt;br /&gt;
:Megan, offscreen: ...&lt;br /&gt;
:Cueball, offscreen: I feel good about things. This is a good game.&lt;br /&gt;
&lt;br /&gt;
:[Cueball sitting on the floor at his laptop, bleeding from the mouth, surrounded by bloody wadded-up tissues and holding a bottle of medication.]&lt;br /&gt;
:Megan, on phone: ...What exactly is in the painkillers they gave you?&lt;br /&gt;
:Cueball, woozy: I can't read the label because I'm a hologram.&lt;br /&gt;
