->''"Yeah, well, tell your disappointment to suck it. I'm doing a {{bottle episode}}!"''
-->-- '''Jeff'''

The study group has finished an assignment for Anthropology class and everyone is getting ready to go on their separate ways. Jeff has a date, Britta has a photography project, and the rest are going to a puppy parade on the quad. Then, Annie notices that her pen is missing. HilarityEnsues as each member of the group is successively accused of having taken the pen.

!!The ''Series/{{Community}}'' episode "Cooperative Calligraphy" provides examples of:

* AirventPassageway: The duct used by Annie's Boobs is huge and well-lit.
* AllThereInTheManual: The DVD case for the first half of Season 2 is styled after Abed's notebook. You can read Abed's notes on the menstrual cycles so that you can see exactly what he wrote without having to freeze-frame the episode.
* AngerMontage: Jeff becomes unhinged and starts ripping out the carpet, tipping over a book shelf and [[TantrumThrowing throwing some tantrum]].
* {{Anvilicious}}: InUniverse, the Equality and Togetherness float at the puppy parade. The Dean, [[PoliticalCorrectnessGoneMad of all people]], lampshades it.
-->'''Dean:''' Okay, now this float feels a liiiiittle preachy. BOOOO! BOOOOOOO!
* BigNo: Annie
* BornInAnElevator: Abed is of the mind that if you are pregnant you should invoke this trope or not be pregnant at all.
* BottleEpisode: {{Invoked|Trope}} by both Abed and Jeff.
* BrickJoke[=/=]ChekhovsGunman: Annie's Boobs the monkey, introduced in Season 1, is the real culprit.
** Abed gives Annie a chocolate in the first two minutes of the episode, long before his menstrual charts are revealed.
** Britta tries and flubs one of the group's rhyming celebrity name jokes (my oh my, Mike Ty... son), which Pierce pulls off successfully (nice try, Stephen Fry) a minute later, to Britta's chagrin.
* CallBack:
** [[Recap/CommunityS1E21ContemporaryAmericanPoultry Annie's Boobs, Annie's backpack, the gum in the hair, and the stolen boyfriend.]] Doubles as {{Foreshadowing}}, since it brings Annie's Boobs back into the viewer's consciousness after a long absence.
** [[Recap/CommunityS1E17PhysicalEducation Jeff's stripey]] [[Recap/CommunityS1E23ModernWarfare Beetlejuice underpants]].
** Abed points out that Shirley could have only conceived during [[Recap/CommunityS2E06Epidemiology Halloween]]. Troy also silently recalls the voicemail Chang sent him at the end of that episode.
* CollectiveGroan: The group's response to [[SoapboxSadie Britta]]'s complaining about "invasion of civil liberties".
* ContinuityNod: The collection of items amassed by Annie's Boobs contains numerous nods to previous episodes.
* TheDogWasTheMastermind: Who would have guessed a little monkey was behind all missing items from the study room?
* EasterEgg: The theft of Annie's pen during the drive-by deaning.
* EatTheEvidence: One of the suggestions.
-->'''Troy:''' Maybe nobody took it. Sometimes I think I lost something really important to me, and it turns out I already ate it.
* EverythingsBetterWithMonkeys: The pen turns out to have been stolen by Annie's Boobs, Troy's monkey.
* FanNickname: While this is certainly not ''Community'''s only BottleEpisode, it's invariably the one any member of the cast, crew, or fanbase is referring to if they say "the bottle episode".
* {{Fanservice}}: Everybody strips down to their underwear in order to find the pen. There's something for everyone!
* {{Foreshadowing}}:
** When removing Pierce's casts to find the pen, Abed expresses uncertainty that they should be doing that, noting that "[[CreateYourOwnVillain this is how supervillains get created]]." Throughout the second half of the series, Pierce's increasingly erratic, {{Jerkass}} and cruel behaviour has been an ongoing subplot, culminating in his revenge scheme in "[[Recap/CommunityS2E16IntermediateDocumentaryFilmmaking Intermediate Documentary Filmmaking]]"; essentially, he becomes the show's equivalent of a super-villain.
** You also notice at the beginning of the episode that when Annie starts to get upset, Abed has a chocolate for her -- hinting at the reveal later in the episode about his tracking the girls' menstrual cycles.
** If you pay very close attention to the beginning of the episode while the Dean gives his non-violent verbal reminder, you can actually see the pen being stolen.
** Later, as Jeff and Troy trash the Library, the camera lingers on the vent where Annie's Boobs will later emerge.
** Britta comments that Jeff "usually" wears Film/{{Beetlejuice}} boxers -- only Abed notices, setting up his realization in "[[Recap/CommunityS2E21ParadigmsOfHumanMemory Paradigms of Human Memory]]" that [[spoiler:they have been sleeping together.]]
* FreezeFrameBonus: On the whiteboard, you can see the phrase "If we evolved from monkeys, how come we still have monkeys?" with the second monkey crossed out and replaced with "Pierce?"
* FunnyBackgroundEvent: During the Dean's announcement about the cold weather affecting the puppies, [[{{Squick}} Pierce is trying to eat the Slim Jim.]]
* GettingCrapPastTheRadar:
-->'''Britta:''' I still think man is going to evolve into woman, not a dragon monster with three legs.\\
'''Pierce:''' [[GagPenis Three legs?]]
* HeldGaze: Jeff and Annie have a very {{UST}}-y moment of holding each other's gaze as their anger ignites after Annie tries to calm down Jeff with the line: "It's just a pen!" The HeldGaze continues even as Britta butts in and Jeff keeps staring at Annie's chest. Once again, the HeldGaze is used to establish that Jeff and Annie's {{UST}} is off the charts!
* HypocriticalHumor:
** When Britta accuses Annie:
--->'''Annie:''' I am ''not'' hiding my own pen, you paranoid weirdo! Everybody stay within each other's eyelines please, one of you is a monster.
** When the group discover Shirley's pregnancy test:
--->'''Annie:''' Guys, this is a terribly childish way to handle this kind of situation. ''(runs over to Shirley and hops up and down in excitement)'' Does this mean you have a new boyfriend? Who, who, who?
** The Dean, who is usually the orchestrator of PoliticalCorrectnessGoneMad, booing the "Equality And Togetherness" float.
** Lampshaded by Pierce, when the study group react with horror and disgust over the discovery that he's been using Slim Jims to scratch his legs, despite having only discovered this by ''forcibly removing his casts'':
--->'''Pierce:''' Have we not gotten to a place free from judgement yet?!
* ICanExplain: Abed, when the group discovers his charts on the female group members' menstrual cycles. Double-subverted in that while he didn't expect them to actually give him a chance to explain, he's prepared with an explanation when they do.
* ITakeOffenseToThatLastOne: Dean Craig Pelton gets called a "non-miraculous son of a bitch."
-->'''Craig:''' Non-miraculous?
* LockedRoomMystery: The situation plays out like this, [[SeriousBusiness despite the mystery being over who has Annie's pen.]]
* MacGuffin: The pen.
* MeaningfulBackgroundEvent: You can see Annie's Boobs take the pen early on, during the Dean's visit.
* MenstrualMenace: Which would explain Annie's attitude in this episode.
* NoPeriodsPeriod: Averted.
* OhCrap: Troy's face when he finds out that Shirley was ovulating on Halloween, [[Recap/CommunityS2E06Epidemiology when she had sex with Chang]]. Doubles as a CallBack.
* ParodyOfEvolution: Apparently man will evolve into a dragon monster with three legs. Or into woman, according to Britta.
* PoliticalCorrectnessGoneMad[=/=]TastesLikeDiabetes: One of the floats in the puppy parade features a puppy and a kitten with the caption, "Equality and Togetherness". [[HypocriticalHumor Even the Dean finds it sanctimonious.]]
* PreciousPuppies:
-->'''Dean Pelton:''' Attention, students! The puppy parade is starting on the quad! Better come quick--[[LampshadeHanging with every passing moment, these puppies grow older and less deserving of our attention.]]
* {{Pun}}
-->'''Jeff:''' I have a date to catch, or, should I say, a catch to date.\\
'''Britta:''' [[LamePunReaction Oof, I hope you just came up with that]].\\
'''Dean Pelton:''' I expect to see you all at the puppy parade. Except you, Jeffrey -- I know you've got a catch to date.\\
'''Jeff:''' ''[off Britta's look]'' Oh, like you're famous for your wit.
* SassyBlackWoman: Shirley.
-->'''Shirley:''' Mother Hen? I think we're about the same age.\\
'''Britta:''' Sure, unless time is linear.\\
'''Shirley:''' I'll make your ass linear.\\
'''Britta:''' That doesn't make any sense.\\
'''Shirley:''' I'll make your ass sense.
* SeriousBusiness
-->'''Annie:''' It's not a pen; it's a ''principle''!
* ShipTease: Jeff and Annie angrily strip off their clothes while using another one of their customary {{Held Gaze}}s.
* {{Squick}}: Britta dumps her bag at the group's insistence. [[invoked]]
-->'''Britta:''' There! Happy?\\
'''Jeff:''' Not if that's a used Q-tip.
* SkewedPriorities: This exchange regarding cutting into Pierce's casts:
-->'''Troy''': Dammit. Broke the scissors.
-->'''Jeff''': Here. ''Be careful''. That's the last pair we have. ''[as an afterthought]'' Also, don't cut his legs.
* TakeThat:
** Jeff's would-be date is named Gwynnifer after [[http://twitter.com/gwynnifer a Twitter troll]].
** [[AuthorTract Jeff]] thinks that the Patriot Act is pretty one-sided.
* TemptingFate: Right after Pierce brags about outbidding three hospitals for his motorized wheelchair and claiming it was worth every penny, it starts malfunctioning.
* TitleOnlyOpening: This is used for the only time in Season 2.
* VictoriasSecretCompartment: Annie is accused of hiding the pen here.
** StealthPun: In the end, Annie's Boobs ''did'' have the pen.
* WhatDoYouMeanItsNotPolitical: Britta provides an in-universe example.
-->'''Annie:''' Last week, she invoked the Freedom of Information Act to request photocopies of my notes.
* AWizardDidIt:The group concludes that a ghost did it.
* WomensMysteries: The response of the women to their finding Abed's charts of their menstrual cycles.
