->''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:

* 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.
* {{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 Halloween, referring back to [[Recap/CommunityS2E06Epidemiology "Epidemiology."]]
** The collection of items amassed by Annie's Boobs contains numerous callbacks to previous episodes.
* CollectiveGroan: The group's response to [[SoapboxSadie Britta]]'s complaining about "invasion of civil liberties".
* 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 "this is how supervillains get created."[[spoiler: 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]]".]]
** 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:
** The theft of Annie's pen during the drive-by deaning.
** 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.
* 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?
* LaserGuidedKarma: Right after Pierce brags about outbiding four hospitals for his motorized wheelchair, it starts malfunctioning.
* 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.
* [[TheDogWasTheMastermind The Monkey Was The Mastermind]]
* 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.
* 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.
* RansackedRoom: The study room is thoroughly trashed by the end, albeit at the hands of the group.
* 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, using another one of their customary {{Held Gaze}}s.
* ShirtlessScene
* {{Squick}}: Britta dumps her bag at the group's insistence. [[invoked]]
-->'''Britta:''' There! Happy?\\
'''Jeff:''' Not if that's a used Q-tip.
* SkewedPriorities: The whole episode. Also, 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]].
* 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 [[ItMakesSenseInContext Abed's charts of their menstrual cycles]].
