* AscendedFanon: A common AlternateCharacterInterpretation for Leonard was that he's always acting so coarse and wild because he's living the young teen college experience he never got to have. "[[Recap/CommunityS2E24ForAFewPaintballsMore For A Few Paintballs More]]" featured Leonard confiding in Britta he has been in several wars.
* BonusMaterial:
** The first season DVD set comes with a short ''Kickpuncher'' comic written by Troy and illustrated by fellow student Jim Mahfood, DVDCommentary, extended cuts of certain episodes, HilariousOuttakes, {{Deleted Scene}}s, the [[Recap/CommunityWebisodes "Study Break" shorts]], and a couple new sketches.
** The interiors of the DVD cases are designed as yearbooks, Greendale brochures and even Abed's notebook from ''Cooperative Calligraphy''.
** Among the many tidbits included are (presumably canon) hometowns for the main characters. Strangely, everyone is kinda paired off in this respect: Jeff and Shirley are from Denver, Abed and Britta from Riverside, Annie and Troy from Greendale itself, and Pierce and Chang are from out-of-state (Wyoming and California respectively).
*** Season 3 episode ''Foosball and Nocturnal Vigilantism'' shows [[spoiler:shared flashbacks of Shirley and Jeff as children, and while they don't specify that it's Denver it does confirm that they grew up in the same place.]]
* CreativeDifferences: Chevy Chase has frequently been vocally dismissive of the quality of the show, with numerous reports of backstage arguments about the direction of the show and his character and a notable feud with creator Dan Harmon. His decision to quit the show in November 2012 came from Chase's displeasure an Pierce's increased bigotry. [[spoiler: He was willing to film a brief cameo appearance in the season 5 premiere, however, suggesting that the rift between himself and Harmon has been exaggerated to a degree.]]
* CreatorBacklash:
** Outside of praising the other members of the cast Chevy Chase rarely seems to have much in the way of praise to say about the show. In part, Chevy would appear to have issues with Pierce's ever increasing bigotry.
** Several of Donald Glover's songs as ChildishGambino have lyrics that can be interpreted, if not outright stating, that he wants to leave the show.
** Dan Harmon had a major backlash to season 4 when he finally watched it after being rehired to the show for the fifth season, to the point he actually apologised over it.
** In a very mild example, Joel [=McHale=] has complained (Notably on the commentary track for "Advanced Introduction to Finality") that the [=DVDs=] only feature the episodes as they originally aired, rather than including extended cuts due to the number of scenes that have to be cut to meet an ever shrinking running time.
* {{Defictionalization}}: Screener [=DVDs=] were packaged with cootie catchers based on the opening credits sequence.
* DuelingShows:
** Originally ran against another PostModern primetime sitcom about a ragtag FiveTokenBand of misfits in school, ''Series/{{Glee}}''.
** Season 2 changes some of the focus to ''ShitMyDadSays'', with a sub plot about Troy's twitter account, [[http://www.twitter.com/oldwhitemansays Old White Man Says]], collecting the insane rantings of Pierce with Pierce wanting to cash in on it with a sitcom. The series premiere of that show was even the same night as the season 2 premiere (which had that Troy subplot).
** In part due to the focus on nerdom in general, and later being put up against each other in the same time slot, there is a certain rivalry with ''TheBigBangTheory''. It's probably more apparently between [[FandomRivalry the fandoms]] rather than anything else.
* ExecutiveMeddling:
** On the DVD commentaries for season one, the producers discuss some of the various ways in which executives got involved in the process. In particular, [[TropesAreNotBad the scenes between Annie and Pierce in "Advanced Criminal Law" were gradually supposed to get a lot nastier in tone between the two, but the executives balked and requested that they be watered down somewhat.]]
** Another example of TropesAreNotBad is that originally, NBC execs demanded of Harmon that half his writing staff were women. He ended up appreciating their skill and kept hiring a large number of female writers even after the comporate rule was dropped.
** After the show was renewed for a shortened fourth season (but moved to a FridayNightDeathSlot), [[http://www.vulture.com/2012/05/dan-harmon-community-future-nbc-sony.html Dan Harmon was fired as showrunner.]] How this will affect the quality of the show is unknown, but according to [[https://twitter.com/#!/CutlerEmily/status/203711765681414145 some]] [[https://twitter.com/#!/meganganz/status/203707622510170112 employees]], it won't be the same.
*** Regarding implications by network brass that he'd stay on as a contractually obligated "executive consulting something or other", Harmon writes on [[http://danharmon.tumblr.com/post/23339272200/hey-did-i-miss-anything his blog]], "Iím not saying you canít make a good version of Community without me, but I am definitely saying that you canít make my version of it unless I have the option of saying 'it has to be like this or I quit' roughly 8 times a day."
* FanCommunityNickname: Greendale Human Beings.
* FridayNightDeathSlot: It was announced that ''Community'' would in fact return for a fourth season...at 8:30 PM on Fridays. Cue fandom terror. And then the show aired in it's original Thursday time slot after NBC cancelled a number of their new shows before mid-season.
* HarpoDoesSomethingFunny: Donald Glover is basically left to his own devices in several scenes.
* HeyItsThatGuy: The show advertises itself this way.
** One commercial specifically referred to Ken Jeong (Senor Chang) as "that guy from ''{{The Hangover}}''."
*** Apparently he teaches Spanish when he's not [[RoleModels commanding an army of LARPers]].
** The actor who plays Abed's dad also plays the principal on [[DuelingShows Dueling Show]] Series/{{Glee}}.
--->'''Jeff:''' ''(upon seeing him approaching)'' "[[RealitySubtext Holy... war.]]"
** [[Series/TheDailyShow Senior Community College Correspondent John Oliver]].
** The accounting teacher/debate coach is [[Series/ArrestedDevelopment Wayne Jarvis]]!
** Donald Glover (Troy) is from moderately well known online comedy troupe Derrickcomedy, creators of such [=YouTube=] classics as "Bro Rape" and"Spelling Bee".
*** For alternative hip-hop fans, it's more of a HeyItsThatVoice - or at least it would be if ChildishGambino[[note]]"Donald Glover" transformed by a "Music/WuTangClan name generator" online[[/note]] didn't openly identify himself as Donald Glover and repeatedly reference his role as Troy in his songs. Dude can rhyme a ''lot'' harder than "donde-esta-la-biblioteca".
*** The rest of Derrickcomedy also cameo as a sketch group that feeds Pierce movie riff jokes in season 1.
** Danny Pudi (Abed) was in several commercials before doing this show, from [=McDonald's=] snack wraps to the Blackberry "butt dialing". He has even appeared as an annoyed customer in a Walgreens training video.
** Wait, how did [[MadMen Trudy Campbell]] get here? Why is she nineteen? Shouldn't she be, like, seventy? And why is she Jewish?
*** Oh my god, you can't just ask people why they're Jewish.
** Oh hey, it's JayJohnston as a police officer, ''[[TheSarahSilvermanProgram yet]] [[Series/ArrestedDevelopment again]]''.
** In "Beginner Pottery", some of the study group takes a pottery class taught by [[Series/ArrestedDevelopment Buster Bluth]] while the others take a sailing class taught by [[Series/TheSixMillionDollarMan Steve Austin]].
** The pool coach is [[BoyMeetsWorld Shawn Hunter]]'s dad! Also, Slinky The Dog in ''WesternAnimation/ToyStory3''!
** Yes, Chevy Chase is now [[SaturdayNightLive ready for primetime]].
** Star-Burns is the creator of ''WesternAnimation/MoralOrel'' and ''WesternAnimation/HighSchoolUSA''.
** [[Film/HarryPotter Lee Jordan]] is Magnitude. Who the hell saw that coming.
** The pregnant girl in Abed's [[MeaningfulBackgroundEvent child-delivery background story]] in The Psychology of Letting Go is [[TheHardTimesOfRJBerger Jenny Swanson]].
** Apparently [[GreysAnatomy Nurse Rose]] has a thing for guys with impossibly good hair, and a pattern of getting ditched for other women and disappearing forever. Sorry, Professor Slater.
** Two of the stoner set are [[{{Chuck}} Morgan Grimes]] and [[Series/BreakingBad Badger]]. Well, at least they're in college...
** This film answers the question of what would have happened to [[AnotherEarth Rhoda on Earth 2]] - she would have gone to community college instead of MIT, and not been a lesbian.
** "Custody Law and Eastern European Diplomacy" has [[{{Dollhouse}} Enver Gjokaj]] as Lukka, again showing his affinity for accents.
** [[Film/GroundhogDay Stephen]] [[{{Glee}} Tobolowsky]] as the ''WhosTheBoss?'' professor in "Competitive Wine Tasting".
** The Vice-Dean of Greendale's Air Conditioning Repair Annex is John Goodman.
** [[TheGuild Zabu]] goes to Greendale and plays Abed in Abed's short films.
** [[Series/TheWire Yo, Jeff. You come at the Biology Professor, you best not miss.]]
** [[FreaksAndGeeks Bill Haverchuck]] grew up to be a Poli Sci teacher.
** Those who saw {{Series/Justified}} first might be alarmed to see psychotic stoner Travis Travers as Dr. Rich.
** Hey, it's PattonOswalt!
** The DragQueen who sang about having a "pocket full of Hawthornes" is none other than [[RupaulsDragRace Shangela.]]
** [[{{Workaholics}} Blake]] doesn't think Pierce is on the list for the Bar Mitzvah.
*** And [[{{Workaholics}} Adam]] is Jeff's estranged half-brother.
** Shut up, Leonard, everyone knows you can [[Series/TheTwilightZone control time]]!
** [[Series/TeenWolf Lydia Martin]] is in biology lab with Troy and Abed in [[Recap/CommunityS1E10EnvironmentalScience Environmental Science]].
** [[LizzieMcguire Lizzie McGuire]] of all people as the school AlphaBitch?
** [[Series/{{Scrubs}} Keith Dudemeister]] is the original [[AnthropomorphicPersonification Subway]].
** Jeff now shares an office with [[Series/BreakingBad Mike Ehrmantraut]], who is just as intimidating as he ever was working for Gus (just ask Leonard).
*** Speaking of Gus, he's Pierce's half-brother.
** Abed's Secret Service "girlfriend" was [[Series/HappyEndings Jane Kerkovich-Williams]]. He also dated a bespectacled [[Film/ScottPilgrimVsTheWorld Envy Adams]] for a short time.
* HeyItsThatVoice: Annie is [[Film/TheLEGOMovie Princess Uni-Kitty]]!
* McLeaned: Chevy Chase's departure being as acrimonious as it was, this was perhaps inevitably Pierce's fate.
* MoneyDearBoy: Despite the critical acclaim and passionate fanbase, Chevy Chase has been very outspoken in his disdain for the show, from calling his decision to join a "mistake", to his run-ins with eventually-ousted Dan Harmon, to criticizing sitcoms as "the lowest form of television." He's stated that the paycheck and his castmates are the only things that keep him showing up.
** Chase appears to have something of a dislike of working in television in general, not just the show, although he has raised a lot of specific criticisms and complaints of the show specifically, including its perceivedly frequent {{Tastes Like Diabetes}} moments. The latter part about working with his castmates being one of the only things bringing him back is also slightly ironic in that his castmates often tend to make fun of him in very public ways (albeit often precisely because he's always dissing the show in public).
* ScrewedByTheNetwork: The firing of Dan Harmon after season 3; cutting seasons 4 & 5 down to 13 episodes, so the seasons never managed to build any momentum; and the show's cancellation at the end of season 5 in the face of the long standing fan campaign for 6 seasons.
* OneOfUs: Creator/DanHarmon.
** Tough-guy actor Jonathan Banks blames his participation in this show on the fact that he's become a regular D&D player.
* ProductionPosse: With Website/{{Channel101}}:
** Abed is based on Website/{{Channel101}} star Abed Gheith, who Dan Harmon pushed for to get the role.
** Fellow Channel 101 alumni Sona Panos, Dave Seger and David B. Lyons work on the series under Harmon.
** Chevy Chase, John Oliver and Joel [=McHale=] all had cameo roles in Episode 9 of Harmon's Channel 101 series ''Water and Power''.
** The Dean Craig Pelton and Professor Ian Duncan are named after Channel 101 stars Dean Pelton and Ian Duncan. Dean told me Dan's just lazy with names.
** Abed's Britta, Abed's Annie and Abed's Abed are all played by 101ers (Jenny Flack, Kelsy Abbott and [[TheGuild Sandeep Parikh]], respectively.)
** The Cast attended the Channel 101 "Channy" awards: Footage [[http://www.youtube.com/watch?v=0tOitMr8a2M here]] and [[http://www.youtube.com/watch?v=mQl5dpoKDfQ here.]]
* RealLifeWritesThePlot:
** Professor Duncan disappears between seasons 2 & 5 due to John Oliver's work on ''Series/TheDailyShow''.
** Pierce [[spoiler:being killed off early]] in Season 5 was to account for Chevy Chase's severance agreement stating he couldn't step foot on the ''Community'' set again.
* TropeNamer: For CampingACrapper.
* WhatCouldHaveBeen:
** [[http://www.avclub.com/articles/community-considered-but-ultimately-backed-out-of,92410/ They were going to do a Nicolas Cage episode.]] [[Recap/CommunityS5E02IntroductionToTeaching They made it.]]
** The statue in the Greendale courtyard was originally supposed to be Mark Hamill, but he declined (and apparently very graciously, according to Harmon).
** According to Harmon, his first two choices for Pierce were Creator/JohnCleese and Creator/PatrickStewart.
** Greg Cromer, who played Rich, was the runner up for Jeff. Had TheITCrowd gotten picked up, he would have gotten the role since Joel [=McHale=] would have been unavailable.
** The show was originally supposed to tell a self-contained story spanning four seasons with a clear beginning, middle, and end. Harmon's firing for the forth season destroyed that, so he ended up having to spend most of the fifth season resetting the status quo in order to resume the story where he left off... just in time for it to get cancelled.
** In "[[Recap/CommunityS5E01Repilot Repilot]]" it is ultimately [[spoiler:a hologram of Pierce that gets Jeff to abandon the law suit against Greendale]]. However, the script used at the table read instead featured [[spoiler:the in-universe reveal that Star-Burns was alive, and he would serve the same purpose as the hologram]]; this was likely the plan if [[spoiler:Chevy Chase hadn't agreed to shoot the cameo]].
* TheWikiRule: [[http://community-sitcom.wikia.com/wiki/Community_Wiki The Community Wiki]].
* WordOfGod: Abed's "quirks" were, according to [[http://www.wired.com/magazine/2011/09/mf_harmon/all/1 this link]] intended to be some form of autism based on [[SelfInsert Harmon's own Self-Diagnosis]] on internet tests, although [[Recap/CommunityS3E03CompetitiveEcology "Competitive Ecology"]] has him imply that he is also [[https://secure.wikimedia.org/wikipedia/en/wiki/Prosopagnosia face-blind.]]
** The girl Abed dances The Lindbergh Lean with in "Urban Matrimony and the Sandwich Arts" is [[http://www.reddit.com/r/community/comments/r258a/theory_girl_dancing_with_abed_was_danielle_harmon/c42bxx7 Danielle Harmon from "Pascal's Triangle Revisited"]]
* WriterRevolt:
** The NBC mandated "Green Week" was lambasted by having the Dean & Enviromental Club waste materials in an attempt to promote Greendale's own Green Week.
** In an example of the ''actors'' revolting, Joel [=McHale=] led the cast in getting Dan Harmon rehired for the fifth season.
