==Explanation==
[[Cueball]] is in a job interview and is being asked prototypical job interview questions by [[Ponytail]], "What is your greatest weakness?", "What is your greatest strength?" and "Where do you see yourself in five years?"

In a roundabout way, Cueball answers that he is a living organism, and as such he has inherent flaws which could cause him to die. This is a reference to the fact that biological systems are "messy" and are not always optimal in design or operation. For example, cancer is a disease where the cellular machinery that governs cell replications breaks down and prolific cell division happens, endangering the organism tumors. While this is a true weakness, it is also a weakness of all biological organisms and is not likely to help the interviewer determine if he is qualified for the job. However, it is likely to help the interviewer determine if he is right for the job -- because the interviewer is likely to know that a person who gives silly and unhelpful answers is not right for most positions.

For the second question Cueball answers that he will one day be the ancestor to all living humans or none of them. As you go farther and farther into the future the ratio of people alive will either go to 0% or 100% of the descendants of the character. The {{w|Most_recent_common_ancestor| most recent common ancestor (MRCA)}} for humans is estimated to have been alive between 2,000 and 4,000 years ago. If the MRCA's ancestors are traced back, the {{w|Identical_ancestors_point|Identical Ancestors Point}} can be found, at which point the entire population are either ancestors all living humans or no living humans. For humans, this point is estimated to be between 5,000 and 15,000 years ago.

For Cueball to be the ancestor to all living humans within 5 years means that all the humans who are not his children or grandchildren, must have died in a near total extinction of the human race. His apparent optimism about the possibility of this occurring is therefore worrisome.

The overarching joke is that Cueball assumes that the interviewer is assessing his fitness as an organism from a genetic perspective rather than his fitness for performing a particular job. The biggest limitation on fitness is survival time and mortality.

The title text takes this further, equating producing offspring during an interview (which would be awkward for all involved) with something that may actually help assess a candidate's efficacy as an employee, namely writing out a sorting algorithm on the spot, another prototypical interview question (see also [[1185: Ineffective Sorts]], especially the bottom left panel).

==Transcript==
:[Ponytail is shown sitting on a swivel chair, to the left of a desk.]
:Ponytail: What would you say is your biggest weakness?

:[The view expands to show Cueball sitting on another swivel chair, on the opposite side of the desk.]
:Cueball: Probably that I'm a giant tangle of parts that don't always work right, so I can die easily.

:Ponytail: Biggest strength?
:Cueball: There will come a day when I'm either an ancestor to ''all'' living humans, or to ''none'' of them.

:Ponytail: Where do you see yourself in five years?
:Cueball: Probably not the ancestor of all living humans yet. But you never know!

Talk:1534: Beer

I hate the taste and smell and associations (such as urine and vomit where they shouldn't be). A friend used to freely admit he didn't like the taste and only drank to get drunk. [[Special:Contributions/108.162.249.161|108.162.249.161]] 06:24, 5 June 2015 (UTC)

This is why there are so many different styles of beers, or wines, or other alcoholic beverages. I personally don't care for IPAs, but will rarely pass up a good Pilsner.[[Special:Contributions/108.162.238.189|108.162.238.189]] 07:37, 5 June 2015 (UTC)

:LOL, that's exactly what Cueball is talking about. Beer is a canonical example of {{w|acquired taste}}. But even after having done so, all hoppy beers (including most IPAs and Pilsners) still taste pretty similar to me. - [[User:Frankie|Frankie]] ([[User talk:Frankie|talk]]) 11:39, 5 June 2015 (UTC)

:: Like of beer is actually a really bad example of acquired taste. I was stealing sips of beer from my dad at age 3-4, if he had an unattended open beer. Liking of beer is primarily generics, and secondary acquired taste. Now talk about {{w|Marmite}} and discuss acquired taste. [[User:Spongebog|Spongebog]] ([[User talk:Spongebog|talk]]) 16:21, 5 June 2015 (UTC)

:::And you, sir, are a canonical example of an ''outlier''. 😜 Seriously though, go to http://google.com and type "is an acquired taste". Google's very first autocomplete suggestion is beer. I'm not saying it's necessarily a ''good'' example, but it is about as canonical as you can get. - [[User:Frankie|Frankie]] ([[User talk:Frankie|talk]]) 03:09, 6 June 2015 (UTC)

Is it possible that the characters, being American, have only ever tasted American beer? So when Cueball says that "all beer tastes kind of bad" hat he really means is "all American beer tastes kind of bad"? That would make a lot more sense (especially if you assume that they only buy from the major brands, and haven't yet tried beer from microbreweries.) --[[User:PeR|PeR]] ([[User talk:PeR|talk]]) 09:30, 5 June 2015 (UTC)
:entia non sunt multiplicanda praeter necessitatem. I think too many people forget Occam's Razor here, and are too eager to engage in deeper analysis than the content can really support without help from, say, an interview with Randall. No offense intended; this is a trend on this wiki in general. [[Special:Contributions/108.162.221.201|108.162.221.201]] 13:18, 5 June 2015 (UTC)

::I'm kind of tired of people automatically assuming is someone doesn't like beer, it's because the person saying so has only been exposed to bad ones due to their locality. I don't like beer at all because it tastes like a mouthful of yeast and medicine. Alcohol in general is an acquired taste for most people, who usually only start drinking it due to social pressure or as a recreational drug. Yeasty foods are as well, especially yeasty breads, and beer is basically fermented bread juice when you get down to it. There's also a genetic link behind whether or not someone will like alcohol, and it's usually he effect rather than the taste that makes it appealing. --[[Special:Contributions/188.114.111.209|188.114.111.209]] 14:45, 5 June 2015 (UTC)

::: You need to read the research -- it is actually linked to genetic differences in taste-buds.

Speaking from personal experience, I've never tried any form of alcohol that I've liked. And if you must know my experience is mainly centered around beer that's highly recommended by friends and family. The last case was at a tour of a local microbrewery that seems to be doing extremely well. I'm sure if I pulled a large scale taste test I'd aquire enough of a taste to delude myself into thinking that something or other is actually worth drinking but I don't see why I should go through the effort just to conform to a social norm. --not the mama[[Special:Contributions/108.162.238.180|108.162.238.180]] 14:30, 5 June 2015 (UTC)

: You should NOT conform to social norm but drink what YOU feel taste good -- 10.000 years ago, humanity needed portable water -- west of the Urals, humans stared to use fermentation as a method to keep bacteria out of the drinking water, where east they started to brew tea -- their descendant responded genetically over the next 10.000 years with European developing genetic traits to be tolerant and liking the fermented brew. Beer is predominantly limited to north Europe as it has lower alcohol levels compared to wine -- the higher alcohol volume is needed to keep bacteria out in the warmer southern Europe -- HENCE unless you are of northen european decent you may not genetically be programmed to like (or tolerate) the taste of beer -- just don't drink beer if you don't like it !!!

::I'm 1/16th northern European (Dutch), 1/4th southern European, Native American too. Guess I didn't get the North Europe beer gene. Why'd the even northerner Europeans like the Russians and Scottish become distilled spirit drinkers? Did their beer freeze too easily so they made vodka and whiskey? If this is why the north developed a beer culture then why'd Egyptians and Mesopotamians drink beer? It's very hot there. [[Special:Contributions/108.162.215.59|108.162.215.59]] 20:08, 5 June 2015 (UTC)

Agreed. Major brands suck, but probably in most countries, even Germany, where people usually have very high opinion about German beer. There are thousands of small breweries, though, some with a very old tradition (like in monasteries), and many just popping up recently. At some microbreweries you have to order weeks in advance, but the brew you get is really exceptional, and you'll drink it at room temperature from wine glasses. Absolutely not meant for getting drunk. [[Special:Contributions/108.162.254.107|108.162.254.107]] 10:47, 5 June 2015 (UTC)

I am disliking to indifferent to most of brands of beer, but I like a few specific ones, like Ginger's Beer, or gingerbread beer from local brewery. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 11:34, 5 June 2015 (UTC)

I know that beer is generally considered to be an acquired taste, but some people acquire that taste really quickly. The first beer I ever drank was a Miller that I stole from a case that my dad had left sitting in the kitchen for months. I was 12, and it is still probably the worst thing I've ever tasted. I decided I didn't like beer, and from ages 12 to 17 the only alcohol I drank was wine. At 17, I tried keg beer and was utterly indifferent to it. By the time I turned 19 I was into good local beers, but if I've been in the heat for a long time, I'll drink watery mediocre beer and it will be divine. And then there's shower beer...oh, shower beer!12:27, 5 June 2015 (UTC) {{unsigned ip|108.162.225.36}}

The only thing worse than a pilsner is an IPA... which is just a stronger version of a pilsner. Most beer just has way too high of an IBU rating. At least malts aren't entirely awful and oatmeal malts are somewhat palatable. [[Special:Contributions/162.158.255.83|162.158.255.83]] 14:25, 5 June 2015 (UTC)

Culturally, for me, the common booze is 'a pint of bitter' (or 'best'). I apparently had my first sip when a toddler. I 'sneakily' took a sip from the top of a glass sat in front of my father, before screwing my face up most amusingly, I am told. I then went straight back in for another... it's not obvious to me if I was being influenced to 'want to like it'. Perhaps it was just the novelty. Anyway, I will admit I don't ''love'' the taste of bitter, but at least it's got an significant taste that all the seemingly anonymous mass-produced lagers can't match. (OTOH, cider's quite stimulating, but I take against the overly fizzy ones.) When it comes to non-alcoholic beverages, I will actively ''refuse'' a cup of tea (the social norm for adults, especially someone like me in their fifth decade), however socially awkward and unexpected, and politely turn down the offer of a coffee, if possible, on the basis that I might not be staying long. (I don't like teas at all, even fruit ones, but I can stand coffee if sweetened.) But it's ''amazing'' what we tend to eat and drink, just because it's expected.

Great comic. This is just for me. I do not like beer. Any kind. And I do rarely drink them. Same with cofee ans tee which I never drink. It is not always easy - so nice to see this comic. :) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:33, 5 June 2015 (UTC)

I'm a stout man (will drink stout alone, if it is dark enough and if the hop content is small enough), but will admit that any beer is better after the fifth glass of it.[[User:Seebert|Seebert]] ([[User talk:Seebert|talk]]) 14:40, 5 June 2015 (UTC)

;"Acquired Taste"

Part of the explanation refers to acquired tastes as being a response to social pressures and to avoid cognitive dissonance. This doesn't match the description of what the '''linked to''' wikipedia page for acquired tastes, as that page distinguishes authentic acquired tastes from those meeting the author's description.

Budweiser tastes like urine. It's the most popular beer in the US. Immediately after trying it I tasted a drop of my urine to see if the urine was still worse and that wasn't enough urine to decide. Anyone care to put a larger amount of urine in their mouth for science? This is the crap they make Bud..Weis..Er and Wassuuuuuuup! commercials about? They actually make a Lite version of this so people can enjoy it while getting less drunk or fat? Extroverts are weird. Also, out of the legion of OKcupid questions the best predictor of the promiscuity question is "I like the taste of beer, true or false". So if you want to have sex quick, you want to hear "Beer tastes awesome! Woo! [Burp] [Vomit] Ooh!Ooh!"

Strangely, many animals acquire a taste for alcohol, and they must do it quickly because they don't live long enough to do it slowly. Case in point-- robins and other birds, gobbling up fermented fallen fruit, and then stumbling around like human novice drinkers do. They only live 2-3 years, and they only have access to the stuff for a couple of weeks in the autumn, and yet, there they go, staggering down the sidewalk and tripping over imaginary twigs. And then there's my puppy, who was begging droplets of strong beer and black coffee off my fingertips from eight weeks old. (Good Canadian beer, by the way.) I wonder if a taste for bitterness might be adaptive, as many bitter plants are also medicinal? [[User:NoniMausa|NoniMausa]] ([[User talk:NoniMausa|talk]]) 22:46, 5 June 2015 (UTC)

Okay, some people don't like beer. That doesn't mean everyone who does is faking it. I gravitate towards IPAs, stouts, rye IPAs and barrel-aged strong beers. I also like scotch, rye, and some bourbons. I fucking love dark roasted black coffee. I savor all of these in company and alone. Stop being so solipsic.[[Special:Contributions/173.245.48.163|173.245.48.163]] 03:32, 6 June 2015 (UTC)

;Placebome

The title of the referenced paper introduces the 'Placebome', the collection of genes which lead to the placebo effect. This is an absolutely ridiculous word, and would be worthy of Jonathan Eisen's [http://phylogenomics.blogspot.ch/search/label/Worst%20New%20Omics%20Word%20Award Worst New Omics Word Award].

It seems more plausible to me that the "they" and "same bottle" in the title text refer to the sugar pills for headache. The title text would then be an organic continuation of the immediately preceding dialogue. [[User:Angew|Angew]] ([[User talk:Angew|talk]]) 09:01, 18 May 2015 (UTC)

I'm confused about why this explanation is a stub. Personally, I think it explains the comic well, but I'll refrain from removing the incomplete tag in case most people think that the explanation isn't adequate. [[User:Caeleste Alarum|Caeleste Alarum]] ([[User talk:Caeleste Alarum|talk]]) 15:21, 18 May 2015 (UTC)

Wouldn't you find a malady that can be treated via placebo, like a headache, give control group A a headache pill, control group B a placebo and tell them it was a headache pill and give the test group a placebo blocker as the placebo and tell them it is a headache pill?

A placebo blocker would be really useful in medical testing to find out which medicines are actually effective and which are simply producing a stronger placebo effect through a noticeable side effect.
[[Special:Contributions/173.245.48.125|173.245.48.125]] 15:46, 18 May 2015 (UTC)

== How to do it. ==

Compound two sets of placebos. The control set is just sugar pills. The other set would be the blocker. Unless the active dose is massive, it'd also be partially a sugar pill already.

Present both as a possible treatment for some malady.

Each group would then only get one pill, and be ignorant that there was potentially a placebo blocker in their dose.
[[Special:Contributions/108.162.238.160|108.162.238.160]] 17:09, 18 May 2015 (UTC)

I would guess that there would have to be at least 6 groups. Groups 1 and 2 would be the traditional experiment with a drug and a placebo, groups 3, 4, 5, and 6 are given two pills one of which they told is a drug, the other is a placebo blocker which may prevent the first drug from helping you. groups 3 and 4 are given the real placebo blocker, groups 5 and 6 are given another placebo. This would be an interesting experiment in that you could test the psychological effects of telling someone who took a real drug that "it may not work."

I think we've entirely overlooked the idea of using a control group that doesn't know what the word placebo means. With such a control group, one could not tell them any lies at all "I've invented this new drug called placebo that will cure your rheumatism".[[User:Seebert|Seebert]] ([[User talk:Seebert|talk]]) 18:57, 18 May 2015 (UTC)

:Why do you have to include the world placebo? Any new made up name like turgidax or pragmanol or frogans or vulpix or bligdrine will work. What is wrong with saying to the patient in the control group,"You are testing a pill of bligdrine." The patient may or may not know what placebo is, but they will certainly be not aware of bligdrine. [[Special:Contributions/173.245.48.163|173.245.48.163]] 20:21, 18 May 2015 (UTC)BK201

1241: Annoying Ringtone Champion

2015-05-10T19:57:41Z

173.245.48.163: /* Transcript */

{{comic
| number = 1241
| date = July 22, 2013
| title = Annoying Ringtone Champion
| image = annoying_ringtone_champion.png
| titletext = It beat out 'Clock radio alarm', 'B-flat at 194 decibels', 'That noise from Dumb & Dumber', and 'Recording of a sobbing voice begging you to answer'.
}}

==Explanation==
This comic satirizes the variety of {{w|Ringtone|ringtones}} that may be used on their cell phones. While many are simply tunes that personalize a user's phone, some will use ringtones that resemble everyday sounds, such as doorbells, coughing, alarm noises, or in this case, the buzzing of a mosquito. Although rather innocuous, these ringtones can get very annoying to some people, which is what this comic is getting at.

The title text refers to four other annoying ringtones, apparently none of which were deemed as annoying as a mosquito buzzing:
*"Clock radio alarm". These sounds are often loud and annoying, just to ensure that you really will wake up.
*"B-flat at 194 decibels". {{w|B♭ (musical note)|B-flat}} is a musical note with a pitch of 466.16 Hz. 194 decibels is the {{w|Sound_pressure#Examples_of_sound_pressure_and_sound_pressure_levels|limit at 1 atmosphere pressure}}. More energy would create a shockwave. This could also be a reference to a crowd of {{w|vuvuzela}}s as they also produce sounds pitched around B flat. This may also refer to several B-flat-related phenomena discussed in an NPR story, [http://www.npr.org/templates/story/story.php?storyId=7442915 Have You Heard About B Flat?] Specifically, B-flat has been found to agitate alligators, and waves passing through gas near a black hole have been found to resonate at a frequency which results in a B flat 57 octaves below middle C. Regardless of all this, a sound played as loud as 194 dB is quite literally deafening, so the ringtone would be not so much annoying as dangerous.
*"That noise from Dumb & Dumber". {{w|Dumb and Dumber}} is a comedy movie from 1994. [http://www.youtube.com/watch?v=0cVlTeIATBs The noise] from Dumb & Dumber is referring to the point in the movie when Harry and Lloyd asked, "Do you want to hear the most annoying sound in the world?" and began shrieking in imitation of a loud fax machine.
*"Recording of a sobbing voice begging you to answer". Self-explanatory. Such a ringtone is obviously disruptive and potentially worrying to those in the vicinity of the phone.
