History Main / MouthfulOfPi

[[folder:Films -- Animated]]

* ''Manga/SayonaraZetsubouSensei'' had a kid recite the first few digits of pi...and get excessively hyped for this feat.
* Kyon of ''Literature/HaruhiSuzumiya'' supposes that the Intergrated Data Entity is smart enough that it "could calculate pi to the hundred millionth decimal point in just two seconds and do all sorts of advanced tricks."
* The first episode of ''[[Anime/HellGirl Hell Girl: The Cauldron of Three]]'' had Enma Ai ask the person she was taking to hell (a teacher) to recite pi while ferrying him there.
* In ''Manga/ThePrinceOfTennis'', one of Sadaharu Inui's {{Image Song}}s has him reciting pi.

* In ''Anime/TanteiOperaMilkyHolmes'', [[PrinceAndPauper Queen Claris (as Sherlock)]] only needs to get as far as "3.14" to convince the others that she's ''not'' Sherlock.
* Ichika from ''Literature/InfiniteStratos'' recites Pi in his mind to [[ThinkUnsexyThoughts force him]] to get his mind off the [[DistractedByTheSexy naked Charlotte who's changing right next to him]] after she dragged him into a changing room both to hide from some [[ClingyJealousGirl girls]] and to show him her outfit. It largely works as he enters a mantra and seems to be determined to recite the numbers.
* Manabe does this in episode 7 of ''Manga/KotouraSan'' in an attempt [[{{Psychic Static}} to prevent Haruka from finding out]] what he may or may not be up to.

* In ''Anime/DigimonAdventure2020'', on episode 38, Joe Kido recites a bunch of things, including [[https://imgur.com/bJ5eL2p the first 41 digits of pi]], to.....combat Mephistomon's ''mind control chant'' on some mook Digimon. Somehow, '''it works'''.
* ''Manga/The100GirlfriendsWhoReallyReallyReallyReallyReallyLoveYou'': In Nano Eiai's introduction, after falling in love with Rentarou and realizing that it's distracting her from studying, she starts writing down an absurd number of pi's digits on her board to stay focused. When it runs out of space, she starts writing them on paper and plastering them over her room before giving up.

* Pi was the basis of one [[MoonLogicPuzzle hideously difficult puzzle]] in the AlternateRealityGame Lockjaw, as chronicled in [[http://www.unfiction.com/compendium/2002/11/15/wheregif/ The Unholy Saga of Where.gif.]]
--> "Day 7: ...Despite the fact that we've spent an entire friggin week on this problem, [[TemptingFate it should be simple high school mathematics from here on in.]] Day 8: [[OhCrap 300 grown men and women suddenly simultaneously realize that they learned nothing in high school math.]]".
* Pi has become something of a RunningGag on ''WebAnimation/HomestarRunner'', so much so, in fact, that [[http://hrwiki.org/wiki/Pi it even has its own article on the site's Wiki site]].
** In one cartoon, Strong Bad receives an email that contains [[http://www.homestarrunner.com/sbemail118.html a computer virus]] that quickly takes over and messes up the website. One character finds himself in [[ShowWithinAShow an issue]] of WebAnimation/TeenGirlSquad. What is the issue number? It is "3.14159265 and the rest"!
* ''WebVideo/LoadingReadyRun's'' [=CheckPoint=] has Graham start to recite all the digits of pi in honor of it being Pi Day, cuts to "Time passes", and then to him finishing, and commenting that it was shorter than he thought. The last number was a 6.
* During one of [=SmallAnt's=] ''VideoGame/SuperMarioOdyssey'' [[https://youtu.be/DWr0aj-xwVQ?t=245 streams]], he mentions that he tried memorizing pi out of boredom while he was in school, and recites it to 40 decimal places to prove he still knows it. He then claims it's really not that impressive or useful to know, and jokes that the ''real'' geniuses are the people [[BoringButPractical who just use the pi button on their calculator instead]].

* Happens in ''Series/CuteyHoneyTheLive'' to show that Honey Kisaragi/Cutey Honey and Miki Saotome/Sister Miki are not normal.

** In [[Recap/DoctorWho20thASTheFiveDoctors "The Five Doctors"]], the correct path across a trapped chessboard is based on pi... somehow. The Master has it memorized well enough to ''dance'' across the chessboard, and the First Doctor knows enough to get himself and Tegan across.
** The Doctor reels off the ''square root of pi'' to thirty decimal places[[note]]1.772453850905516027298167483341[[/note]] in [[Recap/DoctorWhoS30E10Midnight "Midnight"]]. And the possessed woman who's [[StopCopyingMe copying everything he says]] recites it too. At the same time. ''Out of sync by several digits.'' By now everyone's realized that something is very wrong with the woman, but it's at this point when they start getting suspicious of the Doctor, too. Completely PlayedForDrama.

* ''WesternAnimation/TheBatman'' episode [[Recap/TheBatmanS1E8QAndA "Q&A"]] involved the Cluemaster, a bitter ex-child genius hosting a deadly mock game show for the people he believes cheated them out of a win. Rules were simple- everyone gets one question, on any topic. They win and he lets them go free if they can ask him a question he doesn't know the answer to. One of them tries asking him the exact value of pi- he dismisses the question as being impossible to answer, but in the name of being a fair sport, he recites the first one hundred digits just to prove he's not weaseling out of it. [[spoiler:Batman ruins the scheme by asking him "What is the true identity of the Batman?" Ironically, he is actually ''[[SoreLoser not]]'' [[SoreLoser a fair sport when he fails to answer]], attempting to renege on the deal.]]

* Colin from ''Literature/AnAbundanceOfKatherines'' by Creator/JohnGreen memorized the first 99 digits of pi when he was ten by making up a 99-word sentence in which the first letter of each word corresponds to a digit of pi (a=1, b=2, etc.).
** A well-known Real Life rhyme in which the lengths of the words correspond to pi to the first ten places is "See, I have a rhyme assisting my feeble brain, its tasks ofttimes resisting."

* Subverted in Spanish comedy film ''Toc Toc''. One of the characters has a very bad case of arithmomania but when asked about Pi he just says "3.1416" (although he lampshades that he is refraining himself)

** In ''VideoGame/MetalGearSolid4'', Sunny can be heard singing the digits of pi before a Mission Briefing.

* ''WesternAnimation/TheBatman'' episode [[Recap/TheBatmanS1E8QAndA "Q&A"]] involved the Cluemaster, a bitter ex-child genius forcing the people who fixed the game where he lost to play a mock game show. Rules were simple- everyone gets one question, on any topic. They win and he lets them go free if they can ask him a question he doesn't know the answer to.

* If you play as [[Anime/SailorMoon Ami/Sailor Mercury]] in the Sega Genesis ''VideoGame/SailorMoon'' game, she starts off the second level beginning to recite pi before Luna interrupts her.

* No points for guessing what [[IncrediblyLamePun famous song]] Music/PublicEnema used as the framework for their musical mnemonic unofficially titled "[[http://www.alltooflat.com/about/personal/ton/MathematicalPi.mp3 Mathematical Pi]]." Memorize the chorus and play along with MouthfulOfPi at home today!

* [[https://www.youtube.com/watch?feature=player_embedded&v=IazHep3g_rA This]] cover of "[[LightNovel/{{Bakemonogatari}} Ren'ai Circulation]]" is basically just a Creator/KanaHanazawa sound-alike singing the first 400 or so digits of pi.

* In the ''Anime/CowboyBebop'' movie, TeenGenius Ed sings a little song that involves reciting pi. ([[WritersCannotDoMath With a few wrong numbers!]])

* Kyon of ''LightNovel/HaruhiSuzumiya'' supposes that the Intergrated Data Entity is smart enough that it "could calculate pi to the hundred millionth decimal point in just two seconds and do all sorts of advanced tricks."

* In Manga/ThePrinceOfTennis, one of Sadaharu Inui's {{Image Song}}s has him reciting pi.

* Subverted in a FourthWallMailSlot omake of ''Manga/{{Eyeshield21}}'', a reader asked how many digits of pi Hiruma can memorize. He replied, "3.14. If you need more than that, go check it from a book or something." The team mascot commented that he's the kind of guy who doesn't remember useless trivial stuffs.

* Ichika from ''LightNovel/InfiniteStratos'' recites Pi in his mind to [[ThinkUnsexyThoughts force him]] to get his mind off the [[DistractedByTheSexy naked Charlotte who's changing right next to him]] after she dragged him into a changing room both to hide from some [[ClingyJealousGirl girls]] and to show him her outfit.

[[folder:Films — Live-Action]]

* ''Franchise/MetalGear'':

* As noted in the page quote, Fred from ''Series/{{Angel}}'' has memorized 452 digits of pi. In the same scene, the quote comes from, she scares away a homeless guy by reciting it.

* In VideoGame/GhostbustersTheVideoGame, the Stasis Stream Amplifier upgrade has the flow oscillate at pi to the fifth decimal place.
* A character begins mouthing off the Pi sequence in VideoGame/{{Persona 2}} after being challenged by a {{Jerkass}} professor. Only the professor doesn't know if the student's right, as he's an English teacher.

* In [[VideoGame/{{Touhou}} Mountain of Faith]], [[CuteWitch Marisa]], getting bored of going through the stages, grumbles that she could recite pi to a thousand places by the time she got to her destination. Cirno, in [[{{doujinshi}} "A Genius Comes When You Least Expect!"]], one-ups her by claiming to know pi's EXACT value (the last digit, is, of course, [[MemeticMutation 9]]; see Richard Feynman in Real Life below).

* Moe the Clown does this in the second ''VisualNovel/PhoenixWrightAceAttorney'' game. It isn't to show intelligence, it's just one of [[PungeonMaster his many puns]].

* In ''Videogame/RatchetAndClankGoingCommando'', Clank gets repaired by Ratchet, and nearly speaks the ''final'' digit of Pi when he wakes up.

** In a special feature of the first ''Futurama'' movie, there is a math lecture and one of the topics is about pi. The lecturer asks the audience (that is, the Futurama staff which is chock full of math [=PhDs=]) how many digits of pi they know. Eventually, Matt Groening starts rattling off the correct digits...then some nonsense digits before ending with "333...[[CriticalResearchFailure and then just a whole bunch of 3's!]]"
