}}

==Explanation==
An all-you-can-eat {{w|buffet}} is when a restaurant will charge you once for entry and then continuously serve you more food at no additional cost until you have eaten all-you-can-eat. Part of the "[[:Category:My Hobby|My Hobby]]" series, this comic shows [[Randall]] wishes to append "all-you-can-eat" to random stores. These stores do not sell food, so the very idea of eating their product would be ridiculous. However, this is what Randall's stunt makes the stores he defaces seem to advertise. Most people would not seriously consider eating the products these stores sell even with the signs suggesting they should, as it is just a monumentally stupid idea[[[285|''citation needed'']]].

In the title text, Randall seems to have fallen for his own prank. After he puts the "all-you-can-eat" sign onto the signmakers' place, he proceeds to heed his own sign literally and eat the posterboards that he is supposed to make signs from. To remind himself not to make the same mistake again, he tells himself to "do the sign-making place last."

Note that some pets are considered food in some cultures; rabbits are commonly kept as pets as well as served as food, dogs are consumed in some areas in eastern Asia, guinea pigs in South America and Africa, and some fictional characters are known for eating cats[[[285|''citation needed'']]]. Even more normally, a cat owner that wants to buy an "all you can eat" bird feast for their cat would be happy with this last store.

It is not really possible to read the obscured part of the first two signs, although it is pretty clear that the first and last letter in the first sign is A and k. And also since the A is taller than the white sign, this first letter must be larger than the others which do not show above the white sign. There could be room for anything from 8 to many more letters hidden as it can be seen in the second line below that the I's takes up much less space than the other letters. But from the letters below it would be likely there where 9 (maybe including a space) if no I's where used resulting in a word like this "A _ _ _ _ _ _ _ _ _ k".

The last sign is though clearly readable and it says "Kevin's Pet Shop". There actually exist a [http://kevinspetshopcom.weebly.com/ web page with that name], supposedly located in Texas, but there is very limited information on the page. See more about the use of Kevin in xkcd in the [[#Kevin|trivia]] below.

==Transcript==
:[The comic shows the facades of four stores next to each other on a street, with the sidewalk shown in front of them. To the top of each stores name there has been appended white signs. Three of the white signs partially cover the name part of the sign above three of the stores, but the fourth sign is placed entirely above the text of the third store. Thus that white signs top is higher up than the buildings.]

:[First store from the left has one small rectangular section next to the door and then a larger window. The first section may be a poster with information about the store. It could also be a small window. Through the large window (or on it) two rectangular signs can be seen with unreadable text. There are also three half circles at the bottom of the large window, possibly chairs or tires on display. On the normal sized door there hangs an open/closed sign, but no text is visible. On the stores sign the top line of text, likely with the name of the store, is obscured by the white sign so most of the letters are completely covered. Less than half of the first capital letter and ditto for the last letter is visible. It looks like the first letter is an "A", and the last a "k".]
:White sign: All-you-can-eat
:Store sign: Discount Tires

:[Second store from the left has two posters over each other, the top one with unreadable text, the bottom a picture of a person with messy black hair, seen from the torso and up. Next to this is a double door with large windows from below the middle and up near the top. Next to the door there is a small window. On the stores sign the top line of text, likely with the name of the store, is completely obscured by the white sign. This line is shorter than the white sign, but the letters are taller, so top and bottom of the letters can be seen. But is is not easy to guess any letters.]
:White sign: All-you-can-eat
:Store sign: Hair Salon

:[Third store from the left has two posters over each other, but the lower poster is smaller and more to the right. Both has unreadable text, and the top one also some kind of image with two tilted rectangles. Similarly there are three signs above each other with different size and text on the right side of the store. Between them is a large open door. Wider than the double doors of store two, but there is no sign of the doors. Inside the store there are two signs, one hanging down from two rods from the ceiling, both with unreadable text. The one from the ceiling is in the center the other is partly obscured by the door frame to the left. Left and right there are two rectangular structures, which both goes behind the frame. The left is taller. In the middle there is one broad but low rectangular structure with another higher rectangle on top, which does not go to either side of the one below. The white sign on this store is slightly tilted, and most of it is above the top of the store, and thus also almost completely above the store sign. Only the top of the first and last letter in the last word in the top line is touched by the sign.]
:White sign: All-you-can-eat
:Store sign: Lumber and
:Store sign: Flooring Depot

:[Fourth store from the left has a window to the left. Behind the window is a flat surface on which two rectangular structures are standing on their long sides. Over the lowest to the left there is sign with unreadable text. Below the window there is a thins sign with more text. The normal sized door has a window from below the middle and up. There are three several signs up the left sign, and possible another three small signs at the bottom of the window. The top right corner has a curved line around the corner. No text is visible on the door. Next to the door is another square. It could be a window of a place to post things. There are one large posters to the left with unreadable text and to the top right another smaller white rectangle. Below along the bottom of the square there are three small rectangles shown in full, and two more is only partly shown, which could indicate that it is a window and that they are inside the store. On the stores sign the top line of text, with the name of the store, is obscured by the white sign. The name is just a bit longer than the white sign, and as the letters are a bit higher than in store two it can be deduced that it says "Kevin's".]
:White sign: All-you-can-eat
:Store sign: Pet Store

==Trivia==
===Kevin===
*The name Kevin has been used twice before this comic and quite recently.
**That makes this comic the third with a Kevin in only 77 comics:
***In [[1719: Superzoom]], Kevin he worked in a shop that sold superzoom cameras.
***In [[1729: Migrating Geese]], Kevin was the different goose
***In [[1795: All You Can Eat]] (this one), Kevin has a pet shop, with his name in the shops name.
**In the previous 1718 comics there seem to have been no use of Kevin except when referring to real persons like:
***Actors [[1412: Teenage Mutant Ninja Turtles|Kevin]] [[599: Apocalypse|Bacon]] or [[1555: Exoplanet Names 2|Costner]]
***[[1392: Dominant Players|Chess players]] Gariett and Durant.
**So maybe Kevin is Randall's new go to name when he just needs one!
***This has also been discussed in the Geese comic, see the last entry in the [[1729:_Migrating_Geese#Table of labels|table]].

Talk:1766: Apple Spectrum

Well, I did my best on explaining this one... Not really sure I got the Granny Smith part right. --[[User:Andyd273|Andyd273]] ([[User talk:Andyd273|talk]]) 14:32, 30 November 2016 (UTC)

Surely a desert island covered only in apple trees is not beyond all probabilities? [[User:Minimal|Minimal]] ([[User talk:Minimal|talk]]) 15:01, 30 November 2016 (UTC)

I believe his confusion on a desert island with one type of apple is because apples exhibit extreme heterozygosity meaning that any daughter apple tree will produce fruit extremely different from its parent; it would be difficult to have several plants in one area that are all the same that produce no differing offspring (at least on a deserted island...humans can intervene on actively managed orchards). Genetically, the apple does fall very far from the tree. [[Special:Contributions/162.158.59.197|162.158.59.197]] 15:10, 30 November 2016 (UTC)

765: Dilution

2016-10-08T00:01:52Z

Drewthedude64: Transcript incorrectly identifies female as Danish, fixed to label as Megan

{{comic
| number = 765
| date = July 12, 2010
| title = Dilution
| image = dilution.png
| titletext = Dear editors of Homeopathy Monthly: I have two small corrections for your July issue. One, it's spelled "echinacea", and two, homeopathic medicines are no better than placebos and your entire magazine is a sham.
}}

==Explanation==
{{w|Homeopathy}} is the belief that poisons, bacteria, and other harmful substances can actually cure the diseases they normally cause, if they are administered in sufficiently dilute form. The normal procedure is to prepare a solution, then successively dilute it with water or alcohol by multiple factors of 10. (There's also a "succussion" step between rounds, which basically consists of shaking or striking the mixture, but no serious mechanism for how this would affect anything has been provided.) In the medical world, it's widely believed to be total bunk, with countless scientific studies repeatedly showing it to have no more effectiveness than a {{w|placebo}}.

Here we find [[Cueball]], a firm believer in homeopathy, applying the idea to fertility by diluting his semen. 30X means that the semen has been diluted with water at a 1:10 ratio 30 times, so the solution contains 1 part semen to one-nonillion (1,000,000,000,000,000,000,000,000,000,000) parts water. Since the average ejaculation contains 200 to 500 million sperm cells, this means the solution Cueball is holding has a 3.5x10-20% chance of containing even a single sperm cell. Clearly, [[Megan]] will not be getting pregnant from this, so she and Cueball will not be passing on their genes, which is why the comic states that the belief in homeopathy is not selected for.

{{w|Echinacea}} is a genus of flowers commonly used in herbal remedies to stimulate the immune system. Scientific studies have not shown that such an effect exists. The title text is intended to represent a letter to the editors of fictitious journal 'Homeopathy Monthly', starting with a minor complaint that they seem unable to perform the basic proof-reading and fact-checking necessary to correctly spell one of the most well-known herbal remedies. This is followed up by a complete dismissal of homeopathy as a whole and the magazine in particular.

==Transcript==
:[Cueball stands at a desk with a beaker in one hand and a turkey baster in the other. Megan lies in a bed in the same room.]

:Cueball: Okay, this time I've diluted the semen 30x.
:Megan: We'll be ''sure'' to get pregnant now!

:Belief in homeopathy is not, evolutionarily, selected for.

Drewthedude64:

This one seems relatively straightforward. It points out the rabbit hole that comes from attempting to optimize and attempting to fix earlier mistakes.
