Chang's Sanity Slippage at the beginning of season two was supposed to feed into a subplot where Chang would be haunted by the twin sister he ate in utero. The idea was quietly dropped, though it was briefly referenced in "The First Chang Dynasty".
In "Beginning Pottery", Rich is revealed to have severe Mommy Issues. He's seen a few times in season two, but his Mommy Issues are never brought up again.
Academy of Adventure: Between paintball wars, pillow-fort civilizations and vocational secret societies, Greendale campus has definitely grown into this over time.
Adaptation Decay: In-universe, the American remake of Inspector Spacetime shown in "Conventions of Space And Time'' is considered an example of this by Abed, mostly due to the drastic changes suggested by Pierce at the focus group meeting (including making the Constable a blonde Statuesque Stunner and forcing the Inspector to sleep with his own grandmother in 1960's San Francisco.)
Abed: (whispering to Pierce) I hate you.
Adults Are Useless/Apathetic Teacher: a large number of the teachers, and to a lesser extent the dean, are shown to be questionably effective at their jobs. Senor Chang bullies his students, Professor Duncan throws a tantrum and blames a student when his experiment doesn't go like he wanted, and at least one chemistry teacher spends a large portion of a class answering a trivial phone call inside the classroom.
Discussed. Jeff and Annie's relationship is characterized by him being an older brother to her, except that the increasing sexual tension is making that awkward and they can't keep it up, meaning their relationship has to evolve. The discussion ends with "We can't keep doing this, kiddo," with a gentle chuck of the chin.
Annie: Can't we? (long pause) No, it's gross.
Earlier examples have involved similar moments of tension between Annie and Jeff end with him awkwardly patting her on the head.
Affectionate Nickname: Jeff and Annie have addressed one another as "Milady" and "Milord," (respectively) on more than one occasion.
All Love Is Unrequited: The first few episodes seemed to offer a fairly predictable version of this, with alpha-couple Jeff/Britta and beta-couple Annie/Troy. But it eventually averted this, in that after a while the characters decided to move on to other people instead of fawning over someone seemingly uninterested. There is still occasional Ship Tease between these pairings, but it's not a primary focus (and there's just as, if not more, Ship Tease between other pairings, such as Jeff/Annie and Britta/Troy). By season 3, Jeff/Britta and Troy/Annie ship tease has all but disappeared, with Jeff/Annie becoming the primary source of Ship Tease while Troy gets a fair amount of it with both Abed and Britta. Annie and Abed also have their moments.
"Annie, you live in a terrible neighborhood". Annie moves in with Troy & Abed in season 3.
"Documentary Filmmaking: Redux" had the question "Why do I go Greendale?"
Artistic License: For a community college, having alcohol on campus is a big no-no—even if everyone is the right age, regulations and by-laws prevent campus-sponsored activities from including it. This is especially important inS1E11; a lack of alcohol and the subsequent sexy activites would have made the last few moments much less urgent and funny.
Artistic Title: Features a cootie catcher! It changes for a few episodes—the Halloween episodes have spookier images, while the "Advanced Dungeons and Dragons" credits had epic music and medieval-looking script. Then, of course, there's the one-shot animated opening for "A Fistful of Paintballs".
Audience Participation: Of the voting variety. Fans designed their own Greendale flags and then voted for one to become official, the winning one was introduced in "Basic Rocket Science" and the voting was written into the plot as having been done by Greendale students.
Bait the Dog: A very weird inversion. Before the fandom met Andre all they heard about him was nothing but bad things from Shirley. So when he turned out to be Mr. Perfect it jarred so much with the fandoms preconceptions of who he was. As a result many in the community fandom absolutely hate Andre, because they can't see Mr. Perfect as the man who Shirley described.
Played a bit straighter in "Urban Matrimony and the Sandwich Arts" in which, after being Mr. Perfect in his previous appearances, Andre demonstrated a darker side to his character... by which, we mean he got a bit annoyed when Shirley showed up late to their wedding rehearsal, called her 'woman' and demonstrated that he held some rather old-fashioned ideas about a woman's place in married life. This made it a bit easier to see why tensions might have arisen between them and that he wasn't perfect. However, it also rather disproportionately fuelled the hatedom in some places as well, as these flaws were blown up to make Andre look like a misogynistic monster instead.
The Bechdel Test: Easily passes. This may be due to the fact that, unlike most shows, Community's writing team is made up of 50% female writers and 50% male writers.
The first plot involving the women of the study group interacting centers around free speech in Guatemala.
For a short time, Troy and Annie, before Troy started going out with Randy (it can be a girl's name too) and Annie generated some UST with Jeff. Annie clearly still carries a torch, though, based on the loud gasp when Britta says that she and Troy have something to announce.
In season 2, as the Britta/Jeff relationship was developed, there have been moments of Ship Tease for Annie/Abed.
With Season 2 & 3 building up Jeff/Annie, Troy/Britta ended up becoming the new Beta Couple.
One could also make an argument for Abed/Troy as the consistent Beta couple to either Jeff/Britta or Jeff/Annie.
The B Grade: The teachers at Greendale use A-minuses (and minuses in general) as a way to purposely invoke this trope in students they don't like so that they will drop the class out of frustration. One teacher even says they were explicitly invented for this purpose.
Bitch in Sheep's Clothing: The study group (minus Jeff and Pierce, who are more obvious bitches) and Dean Pelton can be this from time to time.
Big Bad: Dean Spreck for the entire series, arguably.
Big Bad Ensemble: In Season 3, Chang trying to take over Greendale, Evil Abed trying to cross over from the Darkest Timeline and corrupt the Prime Timeline until it matches, and Vice-Dean Laybourne trying to bully Troy into joining the Air Conditioner Repair School. And of course, Dean Spreck is shown to still be plotting against Greendale in the season finale.
Big "NO!": Originally Annie but seems to have passed on to Troy.
Bilingual Bonus: The label on the bottle of wine Pierce gives Jeff in "Competitive Wine Tasting" says 'La tua diventa più bello con ogni bottiglia', which translates as 'You become more beautiful with each bottle'
During the season 3 hiatus, the 3-part cartoon, "Abed's Master Key" took a shot at NBC's failure to consider online viewers, which had been determined during the second season comprised the majority of the show's demographic.
The first and last episodes of Anthropology class under Duncan are, fittingly, about death and birth, respectively.
Chang begins and ends season 3 hiding in the air vents but with the latter, he's in City College.
The Tag of the season 3 finale, marking Dan Harmon's departure from the show, ends with the same music that was used in the Cold Open of the pilot.
Season 4 begins & ends with episodes focused on change and what happens when the Study Group start their lives after Greendale. Both episodes also heavily feature elements of All Just a Dream, with Jeff & Abed flipping roles - It's Abed's fears at the start of the season, resolved by Jeff giving a Rousing Speech in Abed's mind; and the other way round in the finale. The first & last lines of the season are also variants of the "Troy & Abed in the Morning!" Mad Libs CatchphraseRunning Gag.
Characters sometimes sip on "Old British 600" and an ill-sized oval changed Jeff's laptop's brand from a Sony Vaio to, apparently, a teapot.
When the security staff is directed to gas the ventilation system with "monkey tranquilizer", the logo on the canister reads "ChimpanZZZZZZ".
Lampshaded by having Leonard post video reviews of Eugenio's frozen pizza and Let's potato chips. The Let's bag is a prop sold by company called Independent Studio Services. (Be warned, the ISS web site is the TV Tropes of props. They make Brand X everything.)
Abed has a whole subplot entirely in the background in "The Psychology of Letting Go" - he refers back to this in "Applied Anthropology" when Shirley goes into labor, to widespread confusion among the rest of the study group.
In "Curriculum Unavailable" the police officer tells the group they shouldn't keep their door open with a brick (as Annie said in "Remedial Chaos Theory") but rather than being for security reasons, it's because the brick is actually valuable.
Greendale seems to be one among institutes of higher learning, especially where local powerhouse City College is concerned.
Britta is the Butt Monkey of the study group. Her constant attempts to be capital-G "Good" (in the most politically liberal interpretation of "good") receive constant groans from the other group members, her attempts to become a therapist are universally mocked (despite having some good results) and "you're the worst" has become so much of a catchphrase that it has now been repeatedly lampshaded. This said, she does bring a lot of it on herself; her attempts to be good (or Good) tend to be hypocritical, inept and backfire disastrously, she often overanalyzes her friends rather ineptly (frequently stumbling into being helpful inadvertently rather than as a consequence), and overall she often puts her foot in her mouth and embarrasses herself.
Chevy Chase on the DVD commentaries, which seem to include everyone but him, and while there will be occasional nice things said about some work he's done, generally he is a walking punchline to the other cast members. And writers. And directors. And producers.
California Doubling: The college is supposed to be located in suburban Denver, but palm trees and cars with California plates are often visible in exterior shots. According to Dan Harmon on the DVD Commentary, the reason it doesn't snow during the show is because global warming hit Greendale pretty hard.
At one point Shirley refers to the "Gerard Butler movie poster with the guy's heart over his wiener". That movie poster is for The Ugly Truth, a movie Yvette Nicole Brown (who plays Shirley) starred in.
While working on his skills as a ladies' man, Abed does a pretty spot-on impression of Don Draper, which Annie really enjoys. Alison Brie, who plays Annie, is widely known for playing Trudy Campbell on Mad Men.
The Black Rider in season 2's paintball finale looks exactly like one of the main characters from LOST, which Abed has a DVD set of according to "Abed's Uncontrollable Christmas".
The biology teacher in season 3 is played by Michael K. Williams from The Wire, which was referenced multiple times in the first season by Troy and Abed. In "Basic Lupine Urology", Williams even says Omar's classic line "a man's gotta have a code."
Vice Dean Laybourne is played by John Goodman. Abed once stated that he loved The Big Lebowski.
In the 'Floor is Lava' episode, Chang lets slip that his same-sex celebrity crush is Nathan Fillion. Guess who plays Greendale's head custodian?
Troy goes from a popularity-obsessed, immature Jerk Jock to a kind-hearted, responsible geek. A lot of this is apparently due to his friendship with Abed.
Jeff learns to care for others and decides to confront his Daddy Issues head-on.
Annie grows up a bit over the course of the show. In early episodes, her insecurity and drive to over-achieve are much sharper. Her youth is also played up: Jeff states that she's too young to be "sexualized," and her fashion sense is one of a prim schoolgirl. In later episodes, her personality softens to be more sweet and sensitive. Coinciding this change, she's portrayed as a more mature woman. Her hairstyle and fashion sense look more mature, and she's even romantically linked to Jeff.
In the Pilot, Britta has "douche-ray vision" and serves as a competent foil to Jeff's jibberjabber. By season 3, douches are her catnip, and she Brittas everything she does. Britta's seismic shift in characterization is referenced by Jeff in season 3, when he points out that she seemed smarter than him when he first met her.
Chekhov's Gun: True to form, Community pulls this off with an actual gun in "Remedial Chaos Theory." Troy discovers Annie's gun the very first timeline we see. Later on, in another timeline, where no one knows about the gun, it accidentally goes off. The stray bullet leads to Pierce's (somewhat) untimely death, which, in conjunction with Jeff's loss of an arm, makes this undeniably the Darkest Timeline.
Chewbacca Defense / Courtroom Antic: Jeff's go-to strategy as a lawyer. He particularly seems to like invoking 9/11. Subverted in at least one instance: when he uses it in "Debate", Greendale loses, 50-8 (and the 8 were to Annie)..
Lampshaded several times in "Comparative Religion", when Shirley's efforts to force everyone to participate in her Christmas party as if they'll completely ruin Christmas Day for her if they don't do exactly what she wants often elicit the response that it's only "December 10th". She later picks up on this; when one of the bullies begs for mercy from Shirley, saying, "Please, it's Christmas!" she responds, "It's December 10th!" and attacks him.
Church of Happyology: Apparently Pierce is in a variation of this, called the Laser Lotuses (which actually seems like a combo of this and Buddhism.)
Clean Pretty Childbirth: Lampshaded in S2, E22: Shirely gives birth in the middle of class. While the trope appears to be averted via Britta's vomiting at the sight of the birth, in the end it's played straight as the birth turns out looking clean and tidy.
The Complainer Is Always Wrong: In "Advanced Documentary Filmmaking," Jeff is convinced that Chang is faking his Changnesia. Then it turns out that Chang genuinely doesn't remember his ex-wife, and now Jeff knows how Chang used to feel all the time - hated and ostracized. Naturally, it was subverted by the end of the episode - Chang really is faking, and is taking orders from someone unknown.
"That makes no sense! Why would I [sexually] harass someone who turns me on?"
"Don't use that word [tardiness] around Abed!"
Jeff: Can you help me block out people's voices I find extremely annoying? Pierce:(discreetly pointing at Britta) Jeff, she's right there...
Troy:(Deconstructing a classic prank on April Fool's Day) Snake in a can? Pierce: No thanks, I'm fasting.
In "The Politics of Human Sexuality", the Dean discovers free condoms handed out by the school are faulty. Fearing pregnancies and the spread of STDs amongst students, he instructs Abed to make an announcement about the condoms over the speaker system. Abed then instructs everyone "if you're going to have sex tonight, don't use condoms."
In "The Psychology of Letting Go", Duncan points out that Jeff's recent desire to belittle and undermine Pierce's faith in his cult is linked to Jeff's discovery that he has high cholesterol. Jeff accepts this, but instead of the expected 'so lighten up about it and let Pierce continue regardless' message, Jeff instead decides that this increased self-awareness means he can really go to town on pulling the rug from under Pierce.
Professor Duncan: No, that wasn't what I w — actually, I don't care.
Creator Thumb Print: All the '80s references from Abed. He doesn't seem to make many from either earlier or later than the '80s, which is a little strange when he's in his early twenties and would've grown up during the '90s and '00s.
Dawson Casting: As of Season 1, Troy and Annie were (respectively) 19 and 18, being played by a 26-year-old and a 27-year-old. Jeff even comments that Annie is still a little too young to be "sexualized," in spite of the actress's age. It's especially weird in light of the fact that Gillian Jacobs is the same age as Alison Brie, but playing a character her own age. It's unclear how old Abed is supposed to be, but Danny Pudi was 31 at the start of the show, and he's never implied to be that much older than Troy.
A Day in the Limelight: The group sets up a D&D game to make Fat Neil feel better in "Advanced Dungeons and Dragons".
Deadpan Snarker: Jeff and Professor Duncan. Britta as well, especially in Season 1.
Jeff:(referring to school mascot the Greendale Human Being, which wears a full-face mask with no eyeholes and is playing Cupid for Valentine's Day) Oh, now it has arrows. That's safe. Britta:(walking in hungover) Oh, now it has arrows. That's safe.
Troy and Annie have gotten good at snark recently
Debut Queue: Variation. A conscious effort was made in the first six episodes to focus on each character of the study group in turn for an episode. In the order they aired, after the first episode introduces Jeff: Jeff partners with Pierce on a class project, Abed enters a film class, Jeff and Shirley bond over gossip, Jeff defends Britta on a cheating charge, Jeff reintroduces Troy to his football past, and Jeff helps Annie with her Halloween party.
In "Studies in Modern Movement," the show points out that Troy and Abed are the funnest guys to be around... In small doses. Living with them while they act out a usual side plot from an episode is very not fun.
The third season has also done a bit of a deconstruction of Jeff and Abed respectively; Jeff's role as Standardized Leader is being examined and his snide, aloof snarkiness has been shown to be concealing a rather messed-up person underneath, while Abed's Ambiguous Disorder has been put under a spotlight to reveal him to be not just a cool, in-control Meta Guy but an inconsiderate, damaged and controlling person to be around sometimes.
Both "Documentary"episodes deconstruct documentaries (and 'Mockumentaries' based on the documentary format), suggesting that for all that documentary makers try to remain objective and present the 'real' events as they occur without interference, the very act of filming random events and building a narrative around them is inherently artificial, and that remaining objective and watching people and events deteriorate around you might do more harm than good.
Jeff's relationship with Britta in season one could be deconstructed in terms of the whole Official Couple/Belligerent Sexual Tension tropes. Instead of truly falling in love, they spent most of the time snarking at each other and competing with each other, to the point where everyone was complaining about in "Modern Warfare". Speaking of which, they finally slept with each other, only to go back to snarky arguments and competition. In the finale, Britta's war with Jeff's ex led to her blurting out that she loved him (the season two premiere revealed that she did not mean it), only for Jeff to leave...and kiss Annie. In short, relationships that are based mainly around snide arguments are likely to be at the very least a bit messed up.
Greendale faced massive deconstruction in the season five premiere, where the school faced major criticism for ruining the group's lives. Basically, it is a look at what happens when a school acts ridiculous instead of ensuring that people actually learn.
The first two episodes of the show include pop songs on the soundtrack.
The first season deals more heavily with Jeff's transition from lawyer to student, and the group is fairly unfamiliar with each other. By the second season, Jeff is comfortably a student and the group members are true companions, plus or minus Pierce.
Parodied with Annie singing a "baby talk" song in a Sexy Santa Dress in "Regional Holiday Music", which also doubles as a dig against the creepy notion of women being sexier when projecting an infantile persona.
Jeff: "Eventually you reach a point of diminishing returns on the sexiness."
Annie: "What's a diminima-mya-mya?"
Fanservice Faux Fight: Buddy's Self-Serving Memory of Britta and Annie in cheerleader outfits fighting over a bra that neither one has in a kiddie pool filled with whipped cream, which he states afterwards "may have been a dream".
Britta's Soapbox Sadie aspect was increased to the point of being a Straw Character, where she'll actively contradict herself within the same conversation just to be Anti-something; at the same time, Britta moved from being The Straight Man to a more sympathetic character, before eventually regressing into the Study Group's resident airhead.
Pierce started out as a misanthropic, bigoted, but generally kind of harmless and Grumpy Old Man, even with occasional hints of a well-buried heart of gold. By Season 2 he's evolved into an overtly evil Manipulative Bastard who plays elaborate, cruel mind games with his only friends, gleefully abuses a suicidal classmate, and shows very little regard for anything except himself and his status in the group. Season 3 dialled him back towards his Season 1 persona, before Season 4 flanderized his Racist Grandpa side resulting in him becoming an extreme racist. The extent of the racism caused Chevy Chase to blow up on the set and quit the show.
The Dean starts out the show as a fairly incompetent dean with an inferiority complex about Greendale. His campiness and sexual eccentricity, first hinted at in episode four when he makes a Freudian slip about "going both ways," gets quickly ratcheted up to him being a pansexual freak who is obsessed with outrageous costumes and stalks Jeff shamelessly. His habit of dropping "dean" into every conversation also starts in episode four and quickly becomes one of his major running gags.
Shirley and her Christianity. Every season she becomes more and more of a hypocriticalChristian fundamentalist. Her high-pitched, lilting sing-song voice also becomes much more pronounced after a while.
Annie moved from being a driven young woman, to an "Awwwwww" machine. Her crush on Jeff has also moved from merely being a smaller aspect of her character to one of the more notable parts of Annie's identity.
Chang has become crazier with each passing season, to the point that Season 5 opens with Chang himself outright admitting to it and moving back towards his Season 1 persona.
Troy and Abed have gone from being merely being best friends, to so codependent on one another that Abed literally can't function without Troy. Individually, Troy has become dumber and more immature as the show has gone on; whilst Abed has gone from being a reasonably functioning adult to suffering a mental breakdown over his favorite TV show being delayed to mid-season, whilst Season 3 has him moving from being a pop-culture encyclopaedia to being almost entirely hung up on Inspector Spacetime, the in-universeDoctor Whoexpy.
The Season 5 premier addresses this, with Jeff pointing out how Britta went from being a socially-conscious anarchist to the show's Butt Monkey, how Troy got progressively stupider and had his entire identity consumed by his relationship with Abed, and so on.
After the revelation that Abed can see the show's Plot Twists coming, he demonstrates Jeff's character trait of actually being bothered by things he pretends not to by showing a clip where he gets distraught that Pierce is at the top of the class. At the end of the episode, it is revealed that Pierce is actually a genius.
In "Advanced Criminal Law", Pierce writes a song about life at Greendale which mentions "taking air conditioner repair", a major plot thread of Season 3.
"In "Intro To Political Science", Troy asks Abed "Do you just constantly have your own little side adventures?" to which Abed bluntly replies "Yep", prompting a saddened "Yeah, me too", in a high-pitched voice. Troy feeling inferior to Abed becomes an important point exploited by the vice dean in the third season, during the build-up to the blanketfort vs. pillowfort war
In "Aerodynamics of Gender", Abed's Robocop sequences foreshadowed the events of the next several episodes, including the blanket forts, Troy's birthday and the Christmas special. One of his mental notes says "Sell Group on Paintball Sequel." A few episodes later in "Intro To Political Science", the news blurbs mention the dean denying another paintball match and suggesting a "Western-themed end-of-the-year picnic". The two-part finale of the season? A Western-themed paintball adventure.
On the opposite side of the screen from the notes during the Robocop sequences are the dates of Britta's, Annie's, and Shirley's menstrual cycles, foreshadowing the events of the very next episode.
In "Epidemiology" Troy becomes the hero and saves the day by lowering the temperature of the air conditioning to get everyone to collectively snap out of their zombie state which foreshadows his affinity for fixing air conditioning units
Forgotten First Meeting: Jeff and Shirley realize that when they were children Shirley humiliated him in a game of foosball. Jeff moved away soon after and they did not meet again until they were adults. The humiliation turned Jeff into the Jerk with a Heart of Gold he is today and Shirley's Heel Realization made her a very passive person.
Freudian Trio - Troy, Abed and Annie since they started living together.
In "Pillows and Blankets", Troy sends a vicious text message to Abed saying that "we all know I was your first friend."
Pierce had been attending Greendale for over ten years, but it would seem that the study group are the first meaningful connection he's made.
Jeff's line of career makes it pretty obvious that he never had anyone he trusted or cared about in his firm.
Chang, for obvious reasons: he's pretty much insane. Despite his efforts, though, he never makes it into the study group.
Britta tearfully remarks at one point that she's never really had any female friends ("Women have always hated me!") and there are hints that most of the people she hung out with pre-study group couldn't wait to be rid of her.
Annie was the bullied awkward nerdy girl at school.
Shirley and Troy didn't have a B-Plot together until the fourth season. Yvette-Nicole Brown (Shirley's actress) noted this in the DVD commmentary for a season three episode where Troy gave a heartfelt goodbye to Shirley, although the two never spent time together on-screen. They also rarely spoke to one another directly even when the group was all together around the study room. This could be read as an attempt to avert any potential Unfortunate Implications of having the only two African-American members of the group hang out all the time, except that it's gone a bit far the other way.
Shirley and Jeff intentionally invoke this because it was established in their first episode together that they were really toxic to one another. This is brought to light again in season 2 where the two almost conspired to get Chang imprisoned for the rest of his life. The third season episode "Foosball and Nocturnal Vigilantism" had a Jeff and Shirley pairing that seemed to resolve their issues and later in the season the two spend an episode together without resulting in them becoming horrible people.
Also Abed and Pierce haven't spent too much time together, but this seems to be at least partially intentional on Abed's end because, as Abed puts it, he doesn't find Pierce all that compelling as a character.
In Season 1's Social Psychology, Abed lampshades the lack of plotlines between him and Annie using Phoebe and Chandler as an example. Although this is somewhat of a parody of the trope seeing as this episode was only the fourth in the entire series.
Full House Music: Common in a handful of episodes and often coupled with a montage. Surprisingly played straight.
In the pilot, this is combined with My Hovercraft Is Full of Eels when Jeff is trying to sell Britta on the idea that he's a Spanish tutor. When challenged to say precisely that in Spanish, he gives a supremely confident delivery that the audience (thanks to subtitles) can see is nowhere close. It is, however, in itself coherent Spanish ("I sleep late Spanish. One more hour. Don't scratch my car."), implying that Jeff knows some limited Spanish (but only what he would need to say to interact with hotel maids and valets) and is pulling a minor Batman Gambit on her, knowing full well that she won't understand it. He even includes the word 'Spanish' in Spanish in the middle because that's the one thing she'll be listening for.
Subverted when the gang walk out on their Spanish final to go and rescue Annie, and as they're leaving each of them talk to the replacement teacher and each other in perfect Spanish. Pierce, however, brings it back to form.
Also Abed talking with his father in Arabic and with Pavel in Polish.
Including, in "The Psychology of Letting Go", an entire funny background storyline. While the main plot of the episode takes place, Abed can frequently be seen in the background meeting a pregnant woman, getting in a fight with her boyfriend, and finally delivering her baby.
In "Abed's Uncontrollable Christmas," a blink and you'll miss it moment when the group is in the Christmas world. As Abed is talking to the group, a snowman can be seen looking at the group from behind a tree. In the real, non-stop-motion world, this would be Chang staring at the group from outside the study room.
Good Adultery, Bad Adultery: Shirley's husband Andre plays with this trope; the negative consequences of his adultery and leaving Shirley prior to the first season are not glossed over, but when we finally meet him and they get back together in the second season he comes across as a decent person who made a mistake, genuinely regrets it and is making a sincere effort to turn his life around and fix things with Shirley. It's also suggested in "Custody Law and Eastern European Diplomacy" that while Andre's actions were the catalyst for the breakdown of their marriage, Shirley herself was not entirely without fault either.
Group Hug: The study groups does this every few episodes.
Averted a lot. Jeff, Abed, Annie, and Troy's parents are all divorced. Also, Shirley's husband divorced her for a stripper though they're back together and have another child now, and Pierce has burned through seven wives.
Abed's films about the gang, especially if you actually watch them.
Buddy in-universe, but the show is so meta, it's hard to tell how obnoxious he is in the show's universe.
Hero of Another Story: There's another, apparently cooler study group, which includes Jack Black, Owen Wilson, Starburns and a hot chick. The study group is this to the other students, since everything turns out to be about them.
Remember when they all took that fishing trip on St. Patrick's Day?
Hollywood Psych: An interesting case of this actually. There are several instances of this in the show, but they're all facts stated by people who are clearly incompetent and ignorant. This is most likely done on purpose.
"Social Psychology": After ranting — at length — about a student evaluation feedback card he received, how hurtful and racist it was, and the lengths he went to in order to discover who the evaluator was:
Señor Chang:[To Annie, very very creepily] Who's erratic and unstable now, Princess Gringa? [Kisses her on the forehead]
"Advanced Criminal Law":
Britta: You know I have a problem with dishonesty! Jeff: You're on trial for cheating!
Señor Chang: That's right, we are mature! Too mature to sit in a class with a cheating, lying poop face!
Annie: Britta, Jeff suffered for us, give him a little credit. Troy: Yeah, you can be pretty cold. Abed: (in the distance) Troy? Troy: Damn. Here comes Abed. He needs my help- I gotta get out of here.
Idiosyncratic Episode Naming: Almost every episode has a name like a community college course (Intro to ______, _______ 101, etc.), though the plausibility of them as titles for real classes gets slimmer and slimmer as the series continues: Season 3 gives us an episode named "Advanced Gay", when something like "Gay/Lesbian Studies" would have been a more realistic class name.
Averted with the pilot, "Abed's Uncontrollable Christmas", the two-part season 2 finale "A Fistful of Paintballs"/"For a Few Paintballs More", and the season 5 opener "Repilot".
Improbably Predictable: Abed is so good at predicting his friends' responses that he can mimic them while they're talking and his videos foretell the future.
Informed Poverty: The college itself. Despite their atrocious reputation and numerous alleged problems, their campus is large and well-maintained, and they have lots of money to use on various plot-relevant events (including redoing 5000 posters, a paintball match, and a large statue, just to name a few).
Irony: Rich is supposed to be better than Jeff at everything. Greg Cromer, who plays Rich, was the runner-up for the role of Jeff.
Jerkass/Jerk with a Heart of Gold: Although Jeff and Pierce are probably the most obvious examples, pretty much all of the main characters have both their jerk sides and their hearts of gold (albeit to varying degrees).
Jumping the Shark: Lampshaded. Many fans consider "Modern Warfare" to be the best episode yet. In the second season Abed has shirts and hoodies made up to give as souvenirs to the people who took part in the paintball game; on the back is printed "It's all downhill from here". invoked
Invoked by Abed. Troy immediately complains that the trope-naming episode of Happy Days was the best one.
Jeff: Gwenifer! Hi, yeah, it's me, I can't make it. Well, tell your disappointment to suck it; I'm doing a Bottle Episode!
Examples of tropes not yet covered by this website, but employed and then lampshaded by the show:
It is revealed to the audience that Troy is in a dance class when he suddenly and dramatically tears off clothes to reveal tights underneath. Later, when encouraged of the positives if he were to reveal his dancing secret to the group, he notes "I have been spending a lot on tear-away clothing."
In the first season finale, Britta is taking therapy with Professor Duncan. She has automatically lain down on the couch for the session, which Duncan notes is how one would act "in a Woody Allen movie" and is unnecessary.
One episode, "Paradigms of Human Memory," lampshades the act of lampshading things.
Jeff: Abed, stop being meta! Why do you always have to take whatever happens to us and shove it up its own ass?
Subverted and lampshaded in "Comparative Religion":
Shirley: What is going on? Troy: We're trying to get Jeff ready for the fi-iiiiiii.... iiiighhhh... t. (whispers) I couldn't think of another word. Jeff: Idiot. He meant we were figh- ...ting. It is hard to think of another word.
Played straight a couple of times in "Physical Education":
Annie: It's just like The Notebook- except, instead of Alzheimers, Abed has— Shirley:(Mm-hmm!) Annie: —someone who... likes him. (next scene) Troy: Abed, for guys like you, this kind of opportunity only comes around once in a li- (looks at Shirley) ...while.
Britta: During high school field trips, we used to sneak in there and get— (glances at Shirley) ...to praying. Shirley: That's nice!
It is unclear when it comes to Troy finding out that Jeff and Britta had sex on the study room table. He starts with what seems to be an agonized "AAAAH!" with Annie and Pierce, then finishes it out as "AAAWESOME!" It's unclear whether he was planning that word from the beginning.
Late Arrival Spoiler: The season two DVD packaging reveals the (admittedly minor) spoiler that for much of the season, Shirley is pregnant.
Laughing Mad: Chang after losing the Pop 'N Lock contest, which the study group doesn't care about.
Dean: Okay, he's bringing us down. Get him out of here.
With Dan Harmon gone from the show as of season 4, the gag is no longer used.
Love Dodecahedron: Jeff started the study group to be closer to Britta, who at one point dated Vaughn, then went out with his (former) statistics teacher who he broke up with in "Basic Geneaology". Annie had an intense study session with Jeff when he joined Debate Club, but still had a serious crush on Troy, until she decided to pursue her relationship with Vaughn. Troy apologized for leading Annie on when he announced he had a date with Randy, quickly explaining that Randy can be a girl's name, too, but (due to some interference by Britta and Jeff) became attracted to Annie, who rejects him for Vaughn. Britta claims she doesn't have feelings for Jeff, but choked onstage when she saw him with an "official" girlfriend, Professor Slater, and Troy had to snap her out of it by "being a friend AND a man." A few episodes later, Jeff and Britta hooked up in the middle of an intense paintball game. In the finale of S1, Slater and Britta both declare their love for Jeff, but he leaves and kisses Annie. Annie and Jeff continue to have big-time UST in S2 and a bit in S3 as well. Meanwhile, Jeff and Britta have been hooking up on the down-low throughout S2, which is brought to an end when everyone else finds out. Annie and Abed kiss in the S2 finale, but only because Abed is in character as Han Solo, and once the paintball game is done he drops character and doesn't reference it again, though Annie is still a bit flustered by the experience. The two of them have a couple of nice Ship Tease moments in S3 as well. Meanwhile, Troy and Britta have more and more bonding moments throughout S3, especially in "Origins of Vampire Mythology", which sets Troy up as the sweet, earnest, good guy Britta's never really had in her life. The amount of lingering hugs and longing looks and other such moments between the two of them, especially in the S3 finale, means that they're the closest thing to an actual couple currently in the group.
Jeff: All right, all right, maybe we're not a family. Maybe it's more complicated, because unlike a real family, there's nothing to stop any one of us from looking at any of the others as a... sexual... prospect... (everybody starts glancing around the table, leading to the entry under Crack Pairing)
As of Season 4, Britta and Troy are an official couple until they amicably break up in "Basic Human Anatomy."
In the Bottle Episode, the reveal that it was the monkey who stole the pen seemingly came out of nowhere. Early in the episode, during the shot where Troy says he wants to lick the puppy Dean Pelton is holding, in the background a tiny monkey hand is seen taking the pen off the table. It is very easy to miss.
In "The Psychology of Letting Go," the background events tell the story of Abed helping a pregnant woman, getting in an argument with the father, and eventually delivering the baby.
Memetic Badass: In-universe, Jeff Winger and the study group - at least according to the Dean.
Mic Drop: Annie Edison finishing her eulogy for Star-Burns.
Britta and her "lesbian" friend from "Early 21st Century Romanticism" are both straight, both think that the other is a lesbian, and both only befriended the other so they could feel hip and progressive for having a lesbian friend.
Money, Dear Boy: 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. 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).
Jeff points this out to Duncan in the pilot episode.
Jeff: Duncan, you did seem less into integrity the day I convinced twelve of your peers that when you made that U-turn on the freeway and tried to order chalupas from the emergency call box, that your only real crime was loving America."
Jeff is being more than a little hypocritical here, given that he's on several occasions a near-perfect example of Moral Myopia. Granted, he is gradually getting better, but even so. One particularly notable example: In the Pilot, having spent the entire episode manipulating, lying and cheating the other members of the study group to get what he wants, he's outraged when Britta reveals she's also been lying to him to try and expose him and when Duncan reveals he hasn't given Jeff the test answers he's been demanding throughout the episode.
Motive Decay: The original reason the study group was formed was so Jeff could seduce Britta. This premise stopped being mentioned about half way through the first season, and towards the end of the third even the study group was temporarily dropped as an excuse to keep the group together. This does not go without a lampshade for long.
Jeff. Particularly in that episode when he played pool.
Jeff: I discovered a new back muscle to work out. Ladies, you'll thank me come tank top season.
Troy's Dracula costume (shirtless with a toilet seat cover as a collar and toilet paper cuffs) during season 2's Halloween episode "Epidemiology". Donald Glover running around cracking wise and fighting zombies without a shirt is nothing to complain about.
All the guys, except Pierce, stripping down to their underwear in "Cooperative Calligraphy." Especially, and surprisingly, Abed.
As of the season two finale, Britta and Annie have wrestled in whipped cream while wearing cheerleader uniforms (and no bras) and in oil while wearing tight t-shirts. Annie's also been covered in paint - which Alison Brie has referred to as part of Community's plot to cover her in as many different liquids as possible.
Mutually Fictional: with Cougar Town. Danny Pudi cameoed in the second-season finale of Cougar Town and it's pretty clear that he's playing Abed. That means Abed lied about lying about being an extra on Cougar Town, although the details are a little different than he described in "Critical Film Studies". In Cougar Town, one character referenced buying the Community box set.
No-Holds-Barred Beatdown: In the episode Intro to Documentary Filmmaking, Jeff threatens to and does attack Pierce, resulting in visible injuries.
Jeff: Oh, I should probably tell you; if you're lying to me, if my father isn't coming, if a car pulls up, and anyone other than my father steps out, say, an actor, you in a wig, if you try to pull any Ferris Bueller, Parent Trap, Three's Company, FX, FX 2: The Deadly Art of Illusion bullshit, I will beat you. And there will be nothing madcap or wacky about it.
No Sense of Humor: Shirley's Unseen Finnish friend Gary is hated by the group in part because he's a humourless buzzkill.
Only Sane Man: Britta came off this way early in Season 1, but Characterization Marches On. Jeff likes to think he is this. However, according to the Britta's psych evaluations in Season 3, Abed is the only one of the group who isn't psychologically insane.
On the commentary track for that episode, Dan Harmon suggests not reading too much into this, because part of his point was that there is only so much about a person's mental stability you can gather from any multiple-choice test.
Whenever he shows up, Shirley's husband Andre comes across as a rather sensible and decent fellow who has plentiful reserves of common sense, in contrast to many of the main characters.
Professor Kane acts as this in season three. "I have so many conversations that have no sense."
Britta: Well? did you talk to Chang? Jeff: Yeah, but... it didn't do any good. My head still hurts from all the yelling... and my pupils are more sensitive to light because he yelled at me so much.
Britta uses them the same way in a later episode. And later that same episode, Jeff and Abed use them... also to hide a hangover.
Out of Order: Unconfirmed, but in Season 1 episode 17 has Jeff say to Leonard "I talked to your son on family day" but family day isn't until the next episode
"Urban Matrimony and the Sandwich Arts" and "Contemporary Impressionists" were aired in that order, but swapped on the DVD allegedly because this is the order in which they are meant to be watched, although that doesn't make much sense either because the latter ends with the beginning of the temporary Troy/Abed breakup, of which there is no sign in the former.
Abed (as Batman) dragging Jeff and Pierce out of the library to Out Run The Collapsing Fort Made Out Of Desks in the Halloween Episode.
In the end of "Modern Warfare" when Jeff leaps out of the study room to escape the blast from Chang's paint bottle time-bomb.
Overused Running Gag: By season 3, paintball episodes. "Curriculum Unavailable" first sets lampshades that paintball's overdone, and then the next paintball episode where they say they "finally figure out how to make paintball cool again" (though opinions are mixed on how successful that was).
Parody Episode: A focal point of the show's humor, starting with the second half of the first season, various episodes devote themselves to being parodies of various genres:
"The Science of Illusion": Annie and Shirley try to be a crime drama-esque buddy cop team, with each one trying to be the loose cannon bad cop.
Let's face it, pretty much everything involving the Dean is an example of this. Case in point: "Alternative History of the German Invasion" has the Dean slamming on the obnoxious German trio for celebrating Oktoberfest (along with everyone else), because it's their own tradition and therefore a national stereotype. Or something.
Pop-Cultural Osmosis Failure: Occasionally pops up due to the age gaps within the study group (from Pierce to Jeff and Shirley to Annie and Troy) and to a lesser extent due to the race differences:
A conversation about the UST between Jeff and Britta:
Shirley: You remind me of Sam and Diane... I hated Sam and Diane. Annie: Who's Sam and Diane? Shirley:[furious] Okay, we get it! You're young!
When attempting to convince Abed to change his personality in order to help him talk to a girl:
One of the 'Study Break' webisodes has the gang decide to play a game while on a study break. Troy, Annie and Abed decide to play 'The Floor Is Lava', Pierce and Shirley break out the cards to play Pinocle, and Jeff and Britta find themselves trapped between the two poles. Lampshaded when Jeff dryly taunts Britta by pointing out that "the generation gap is splitting our group — and you're right in the middle of it."
Shirley repeatedly makes a point of reminding everyone that she and Jeff are about the same age—she just seems to be further removed in age because of her more old-fashioned, conservative views and the fact that she is a parent while Jeff is not.
Post Modern: The show repeatedly takes dialogue, scenes, shots, premises, and songs directly from other works (about higher education or otherwise) and notes it.
Interestingly, David Foster Wallace predicted that just this show would appear... in 1990. Had he lived to see Community, his reaction would have been a mixture of horror, fascination, and amusement.
Pottery Barn Poor: A source of contention for fans is the fact that the sources of income for almost all the characters are unclear. Of the main characters:
Jeff is briefly homeless in an early season 1 episode, indicating he must not have had much money saved from his former lawyer job. However, in all later episodes his financial status is fine. Up until the "season 3 finale," many fans assumed he consulted at his old firm, but Alan debunks this by telling Jeff about events that have happened since he stopped working there. Jeff has been shown to live in an apartment.
Britta is repeatedly established as being poor. Of the younger characters, she is the only one ever seen with a job—in "Critical Film Studies", she works at a diner, but gets fired at the end of the episode. Britta is also known to live in an apartment.
Troy lives with his father in the first season, but gets kicked out and goes to live with Pierce. In the third season, he and Abed live together in an apartment, but their source of income is never revealed.
Abed is the only one who lives on-campus in the two seasons, and then lives together with Troy in an apartment in season 3. He actually gets into debt with a celebrity impersonator company, revealing he has no source of income. Abed seems to have depended entirely on his parents until arriving at Greendale, and it's possible that his father still pays for his bills.
Annie's financial status is actually the focus of an episode, "Celebrity Pharmacology". A recurring claim throughout season 2 and early season 3 is that she lives in an apartment in a "bad neighborhood." She tells Pierce that she pays her bills with money she saved from every birthday and special occasion (such as the "period fairy") she's had, which, although unrealistic, is at least more than can be said for the others. However, she runs so low on money that she is forced to take a bribe from Pierce. At the end of the episode she says she plans to get a job, but this has never been elaborated on. Some fans jokingly think she works at Dildopolis, the sex toy store below her apartment. In season 3, she begins living in Troy and Abed's apartment.
Shirley, as a single mother, presumably received child support and alimony from Andre. They later reconnect and get back together. Later, she begins attempting to start her business, and Andre implies that he is the breadwinner of the family.
Pierce is rich and the heir to his father's fortune, although he chooses to give it up to his half-brother Gilbert Lawson. He presumably has a large fortune for himself.
Chang in Season Two. It's doubtful the school was paying him to show up to classes, given how grievous his resume-falsifying was, and he flat-out tells Jeff that his wife kicked him out in "Early 21st Century Romanticism," depriving him of whatever income she had. It is worth noting that Chang lived inside Greendale for an undefined amount of time.
Precision F-Strike: In the episode where the group is visiting Pierce in the hospital, and he is using it as an opportunity to screw with them, he tells Jeff that he located Jeff's real dad. Jeff knows that Pierce is almost certainly messing with him, so after saying that he will go see him, he turns and says: "Oh, I should probably tell you; if you're lying to me, if my father isn't coming, if a car pulls up, and anyone other than my father steps out, say, an actor, you in a wig, if you try to pull any Ferris Bueller, Parent Trap, Three's Company, FX, FX 2: The Deadly Art of Illusion bullshit, I will beat you. And there will be nothing madcap or wacky about it."
The Present Day: A rare example of a show that literally takes place as much in the present day as possible; it is implied episodes are taking place on the very same timeline as they're airing. On two occasions, characters have referenced the events of the previous week's episode as having happened last week. The first season's Christmas episode aired on December 10, 2009 and takes place on December 10, 2009; more subtly, "Conspiracy Theories and Interior Design" featured a Latvian Independence Parade, and aired on November 18 — Latvian Independence Day. The time when the season takes place (mid-fall through spring, usually with a break in the winter) corresponds with the time that most colleges are in session, even to the point that the mid-season break is the break between fall and winter semesters and the customary re-run period over spring break is the break between winter and spring semesters. So doing the episodes in a real-time weekly structure works.'
This is also why "Paradigms of Human Memory" is so effective—compared to what we see in the episodes, there's tons of stuff we don't get to see, including entire episodes revolving around a ghost town, a haunted house, a shark hunt and a St. Patrick's Day rafting trip. Even when the cameras aren't on, the characters are still doing things.
Similar to the Latvian Independence Day example, the upcoming pillow vs. blanket fight episode is airing on National Pillow Fight Day.
Averted so far in season 4, which was delayed till February 2013 and yet its first episode still takes place on the first day of school in the fall.
Present Day Past: The supposedly 1980-vintage RV based space simulator included flatscreen displays and the glimpse we got of the actual RV dashboard was considerably more modern than it "should" have been.
Many other people involved with Channel 101 work on the show (see the Trivia page for more info).
The other members and acquaintances of Donald Glover's sketch comedy group Derrick Comedy have a cameo helping Pierce write jokes in "Romantic Expressionism". (D.C. Pierson had previously appeared in "Investigative Journalism".)
Also, no one likes Shirley's (never-seen) friend Gary.
The Dean's dalmatian-furry fetish is followed from its very beginning ("I hope this doesn't awaken something in me"), to its escalation (dalmatian mugs, posters, and rugs), to its inevitable conclusion in "Pascal's Triangle Revisited".
Troy and his propensity for "butt-stuff."
People like to comment on the size of Jeff's forehead. By the end of season 2 he starts getting insecure about it.
The first season commentaries continuously allude to (the non-drinking) Yvette Nicole Brown being an alcoholic.
As well as Britta's "skankiness" (although Gillian Jacobs is the first one to use the term).
Season 2 involved a lot of diorama-making, including a diorama of them making a diorama.
Annie: I heard someone made a diorama about a world without dioramas.
Season 2 alsi involved no-one knowing what Anthropology is actually supposed to be about. Including the Professor teaching the class.
Season 3 seems to have a theme of new characters not 'getting' the show mechanics.
Also everytime the Dean leaves the study room, he touches Jeff.
The racist and anti-racist jokes.
Chang's inability to recognize backhanded compliments.
Pierce getting mistaken for dead.
On random occasions throughout Season 3, characters can be heard humming Michael Haggins' "Daybreak." It spreads from character to character.
It starts with Abed humming it as part of his 'horror story' in "Horror Fiction in Seven Spooky Steps." In a later episode, Troy (who was the only one who enjoyed Abed's story) hums it as he leaves the blanket fort and sees that Annie broke the Dark Knight DVD. Then, a few episodes later, Annie hums it as she goes outside to talk to Jeff. Finally the song is played for real when Neil plays it over the school radio in the pillow war.
Jeff's "blow off" class always becoming more important than he thought.
Seemingly mundane, innocent and everyday things being blown up to Serious Business levels by either the study group or Greendale as a whole.
Annie swooning over Abed's impersonations.
Halloween costumes: Jeff is always 'accidentally handsome' (handsome cowboy, David Beckham), Annie is obliviously sexy (lycra skeleton costume, Little Red Riding Hood), Britta never makes any attempt to be attractive (squirrel, dinosaur), Pierce dresses as sex symbol from his youth (Beastmaster, Captain Kirk), Shirley's costume is always "unintentionally ambiguous" (Harry Potter [mistaken for Urkel]), Glinda The Good Witch (mistaken for Miss Piggy) and Abed's costumes reference his favourite films (Batman, Alien).
Magnitude greeting everyone (and everyone greeting Magnitude) with "Pop pop!" According to Donald Glover, it's "so not a catchphrase it becomes a catchphrase again."
From the behind-the-scenes footage, Alison Brie's rapping and predilection for handjob jokes. In the second outtakes reel the others start impersonating her doing the latter.
In the season 3 commentaries, Joel McHale always introduces himself as somebody else, usually as Alison Brie.
In season 3 (especially the second half), a character will ask a brief request of three different characters individually using the same word or brief phrase while pointing at them. ("Intervention? Intervention? Intervention?")
The group (but mostly Annie and Shirley) saying "Awww!" in unison, and the Collective Groans to Britta's self-righteous statements.
Troy saying: "Pretend like you're asleep!"
The study group's habit of saying something aggressive, then rhyming it with a famous person's name.
"TROY AND ABED IN THE MOOOOOORNING!" and the numerous variants.
Various people (even a priest) telling Britta "You're the worst!"
One character interrupting another by blurting out "let him/her finish!" when they mistakenly expect him or her to be cut off mid-sentence by the rest of the group.
Annie being reminded that she lives in a terrible neighborhood.
Annie & Troy don't understand some pop culture references because they're too young.
Annie makes a point of pointing this out when she sarcastically thanks Jeff and Britta for ruining her love life.
Abed has to go into this:
Abed: Oh, that's sarcasm, but I forgot to inflect. This sounds way more like sarcasm. Inflection is so interesting.
Abed: You shifted the balance, like in a sitcom when one character sees another one naked. Jeff: Is that really a sitcom staple? Abed: You're right, what do I know. I'm Abed, *derp face* I neeeever watch TV.
The Scrappy: Vaughn, in-universe example. Another in-universe example is Shirley's friend, Gary. (Troy: "I hope he transfers to HELL!")
Secret Handshake: Troy and Abed's secret handshake is not particularly secret, it's just their usual handshake followed by both of them whispering "SECRET".
Duncan refers to leaving his wallet "in the back of my lorry", presumably because someone heard that 'lorry' is British English for 'truck'. In fact it suggests that the psych professor mysteriously owns an 18-wheeler - pickup trucks are hardly ever seen in the UK, and when they are they're called 'pickup trucks'.
Not to mention that, as shown in the pilot, Duncan doesn't have a pickup truck at all; he drives a Smart car.
Duncan also states that he grew up on "52nd Street in Islington". Assuming he means Islington in London, not only is there no such street, but in British cities streets are usually named, not numbered in the same way that they are in American cities.
In-universe example: "Let's blow this pop stand and head out back for a spot of slap and tickle. That's sex, in case the lingo hasn't made it across the pond."
...all of which are part of the larger joke that Duncan doesn't actually know any English slang and knows very little about England, having come to the US at a young age with his grandfather.
Serious Business: To the point of a Running Gag; it seems that there is nothing on Earth that either the study group or the wider Greendale community as a whole cannot take and find some way to completely blow out of proportion. Such as:
Chicken fingers are so important that the gang starts a mini-Mafia to control them.
Paintball, as shown in "Modern Warfare", "A Fistful of Paintballs" and "For a Few Paintballs More".
Losing a pen leads to the Study Group literally tearing the study room apart to find it.
In ''Early 21st Century Romanticism" the group are just as — if not more — outraged by Jeff's dislike of the Barenaked Ladies than his reluctance to join them in an intervention for Pierce.
The rivalry with City College - up to and including a 'space race.'
Love of the game of pool is treated this way in "Physical Education."
The Air Conditioner Repair Annex is basically a cult, complete with their own by-laws & traditions.
Picking lab partners, instead of being a quick & painless task, took the Study Group an entire day to get done. And even then, they didn't actually do it.
The decision whether to make a blanket fort or a pillow fort turns into a campus-wide pillow-fought civil war in "Digital Exploration of Interior Design" & "Pillows and Blankets".
Abed and Troy's 'Dreamatorium' - they would rather sleep in a tent within their apartment than use the room as a bedroom.
Someone pushing a yam off a table in "Basic Lupine Urology".
"Alternate History of the German Invasion" reveals that the group treat anyone else using Study Room F as an invasion of their home, whilst the Study Group hogging the room leads to the rest of the student body protesting against them.
Someone else using Magnitude's "Pop pop!" catchphrase leads to him having a nervous breakdown & crisis of identity.
The Ass Crack Bandit, who runs around Greendale dropping quarters down people's ass cracks when they're bent over, is treated like a police force would a serial killer. This is gradually subverted towards the end, however; when the study group learn of the death of Pierce, they immediately recognise the Bandit as ultimately trivial in comparison to the death of their friend.
Sexy Shirt Switch: Parodied/referenced/somethinged during Troy's and Abed's "supercool elevator" mime act.
Shameless Self-Promoter: Joel McHale spends a lot of time on his E! Network show The Soup urging people to watch Community.
Mocked mercilessly with Jack Black's appearance as "Buddy" a student who has allegedly been in the gang's Spanish 101 class this entire time. The entire main cast are either weirded out by his sudden, unexplained appearance in their lives or convinced he's a murderous psycho. The episode ends with Owen Wilson suddenly appearing and offering Buddy a spot in the "cool" clique.
Professor Slater - NO ONE is on Team Slater.
Shout-Out: The show does this a lot. Examples from individual episodes are listed on the Recap pages.
Super-meta Abed writes and directs a campus TV show called The Community College Chronicles, with characters based on his study group. Abed's so well-versed in TV tropes that he can use the show to predict what's going to happen to the study group next, down to Shirley being chased through the library by a werewolf - also making this a Type 4 example.
Hilariously played with in the season 4 premiere, where Abed is told to go to a happy place in his mind. Cue an alternate multi-cam style version of the show (complete with laugh track and fake banner ads) playing on "Abed TV," followed by a cartoon version inside that one, where everyone's a baby. As Leonard so aptly puts it, it's "show-ception!"
Society On Edge Episode: This is a recurring situation. Greendale Community College is a sucky school and the students tend to get more volatile and over-the-top as finals approach. The major breakdowns occur once a year in-universe; which corresponds to one per season. In the past this has twice resulted in paintball competitions totally wrecking the school. In season three, the school loses most of its funding so things get even worse. An attempt to achieve a world record for the biggest blanket/pillow fort results in a civil war and a short time later the wake for a deceased student turns into a riot.
"Digital Estate Planning" has the study group's portraits being rendered into 8-bit avatars in preparation for the video game they're about to play, complete with the title theme in instrumental 8-bit.
"History 101" has Abed singing a rewritten version of the theme as part of his imagined "Abed TV" sitcom.
"Basic Intergluteal Numismatics" has a montage over the evidence and news reports of the Ass-Crack Bandit as an Homage to the opening credits of Hannibal.
LeVar Burton appears as himself in "Intermediate Documentary Filmmaking".
French Stewart appears in "Contemporary Impressionists" as a guy who used to be a professional French Stewart impersonator.
Springtime for Hitler: In "Advanced Documentary Filmmaking," Jeff does his damnedest to sabotage the attempt to get a grant from the MacGuffin Neurological Institute for research into Changnesia, part of which includes having Pierce put on an incredibly racist puppet show. Needless to say, it backfires miserably.
Stealth Pun: Most of the show's episode titles relate to the A- and B-plots of the episode. So at first glance, "Digital Exploration of Interior Design" doesn't make any sense. Until you remember that Britta and Subway did something in the pillow fort...
Stereotype Flip: Señor Chang the Spanish teacher goes on at great length about this.
He does embrace the Asian love of gambling displayed in the pool episode when he takes bets from the surrounding crowd, though.
In "Basic Genealogy," it is revealed that Señor Chang's brother is a Rabbi. This is lampshaded by Dean Pelton (though he also mistakenly assumes that the Changs are Japanese).
Dean: Well, it was wonderful meeting your brother. Adios Señor Chang, Shalom Rabbi Chang, and to both of you, Sayonara.
Stepford Smiler: Annie's parents, who would've covered up her drug addiction rather than support her in her decision to go to rehab.
Annie (covers up her insecurities), Shirley (has a Dark and Troubled Past) and Dean Pelton (afraid that Greendale isn't good enough).
Studio Audience: In a very weird example, Joel McHale and Ken Jeong hosted a running commentary for a Community marathon between seasons 1 and 2 that had a studio audience. At one point, for no reason at all, the entire audience walked out.
In "Intermediate Documentary Filmmaking" Abed takes aim at mockumentary shows like The Office and Modern Family: "It's much easier to tell a complex story when you can just cut to the characters explaining things."
In "Critical Film Studies", Jeff lists "watching Cougar Town" as one of Abed's eccentricities that makes it seem like he's determined to make people not like him.
In "Biology 101" when Abed learns CougartonAbbey is only 6 episodes, Britta states how British television actually gives closure to its shows.
Jim Belushi is a favourite punching bag on the show:
Jeff: The biggest truths aren't original. The truth is ketchup. It's Jim Belushi. Its job isn't to blow our minds, it's to be within reach.
Prof. Slater: (later in the conversation, about Jeff's fear of the word 'boyfriend') Whoopdie-freakin'-ding, Winger. It happens 50 million times a day. It's the Jim Belushi of sexual commitments. It barely means anything and it grows on what's there over time.
Jeff: Boy, that guy's really taking a pounding in this conversation.
Jeff: (practicing a wedding toast) Webster's Dictionary defines-
Annie: Aaaagh! Stop! 'Webster's Dictionary defines'? That's the Jim Belushi of speech openings. It accomplishes nothing, but everyone keeps using it and nobody understands why.
Evil Abed: Do you know what kind of person becomes a psychologist, Britta? A person that wishes deep down that everyone more special than them is sick because healthy sounds so much more exciting than boring. You're average, Britta Perry. You're every kid on the playground that didn't get picked on. You're a business casual potted plant, a human white sale, you're VH-1, Robocop 2 and Back To the Future 3, you're the center slice to a square cheese pizza... actually that sounds delicious... I'm the center slice to a square cheese pizza...You're Jim Belushi.
Parodied in one episode with Jeff as the Team Dad, Britta as the Team Mom and Pierce as their kid.
(Jeff is at a water fountain; the rest of the group gathers around him expectantly) Jeff: Look, if you guys just let me get to the can opener, I can feed you.
Troy: Hey! You don't get to talk to me like that! You are not Shirley! ...And Shirley's not my mom!
Deconstructed in "Comparative Religion"; normally Shirley is a benevolent Team Mom, but in this episode her ability and tendency to use this role to be smothering, passive aggressive and emotionally manipulate her friends through guilt trips is noted and called out, and it's pointed out that since she's not actually their mom she has no right to act in such a fashion.
Toilet Humor: The "Creative Compromises" featurette on the season 1 DVD is presented as a way for Harmon to show us what his cut of some scenes from "Football, Feminism and You" would've been. It changes the "Britta deals with her lack of female companionship" plot to "Britta has a flatulence problem."
Pierce: You, me, Jeff, Rainman, Big Boobs, Medium Boobs, and Black Boobs - we're a family. Troy: ...am I Black Boobs?
Ultimate Job Security: All the teachers never get fired, despite how sadistic or incompetent they can get. Lampshaded in at least one episode; after complaining to the dean, Annie mentions that they've been trying to fire one teacher for three years, but no one else wants the job.
Jeff's not a complete jerk, but he definitively leans towards the Jerkass side of Deadpan Snarker, and for sure most of his problems are his own fault.
Also Pierce, to the extent that he's the protagonist.
Vague Age: Of all the main characters, Abed is the only one whose age is completely unknown. Danny Pudi is 33, but his youthful appearance and Abed's social awkwardness and Man Child behavior make it difficult to tell how old he is supposed to be. Most fans assume he is somewhere in his early 20s, like Annie and Troy, but this has never been confirmed. Additionally, his development and childhood appear to have been heavily influenced by 80s and early-90s pop culture, suggesting he may be at least a few years older than Troy and Annie (born in 1989 and 1990, respectively). However, in one of the internet shorts, Abed participates in the "Floor is Lava" game with Troy and Annie, and he is usually grouped in with them when jokes or comments about the younger members of the group are made. In an early pilot script, Abed was said to be in his "mid-20s," at the same time when Annie and Troy were 18 and 19, although all the characters were substantially different in that early draft.
Weaponized Offspring: While playing the in-universe video game "Journey to the Center of Hawkthorne" Abed reprograms his NPC wife to birth babies (which look like tiny versions of Abed) and uses them to fight the final boss.
What Could Have Been: The Luis Guzmán statue would have been Mark Hamill, but the actor graciously declined in a letter to Dan Harmon. Picture "Documentary Filmmaking: Redux" now.
What Happened to the Mouse?: Professor Slater vanished into the ether after season one. Although in the episode "Intro to Political Science", it is noted by Troy and Abed's Campaign Followup that Prof. Slater is missing. Word of God is that Harmon was simply tired of the character.
Professor Duncan became a case of this after Season 2 (it was even lampshaded in Season 4). He returned in Season 5, having spent the last two years caring for his ailing mother.
Does Troy still play football for Greendale?
We never do find out why Starburns faked his death.
Dean Spreck's next evil plan to destroy Greendale, after getting a huge tease at the end of Season 4's penultimate episode, has not been revisited.
"Contemporary American Poultry" is Goodfellas, including the narration and even using Layla when showing Abed's control measures.
Troy's subplot in "English As A Second Language" is Good Will Hunting with faucets. So really, just in reverse. Word of God, this was intended as a Take That. This is made clear by the fact that rather than going along with the movie parody, Troy resists it. When Abed uses the same line as Ben Affleck - "the best part of my day is when I think you're not going to be there", Troy rightfully takes offence at it.
In season 2, Annie references herself and Jeff with this trope.
By season 3, Troy and Britta did this too. As of season 4, They Do.
Women Are Wiser: Subverted. While at first glance it may appear as if Britta, Annie, and Shirley are the more normal ones in the group as opposed to Troy and Abed's wackiness and Jeff and Pierce's meanness, a closer look reveals that the girls can be just as crazy as the guys, they're just better at hiding it. In the episode Aerodynamics of Gender, Jeff and Troy find serenity and perspective, while the girls are consumed by hateful activities and dominant behavior.
You Kill It, You Bought It: Pierce's dad dies of a heart attack (after being yelled at by Jeff). Having written in his will that whomever kills him will inherit his ridiculous looking ivory toupee, it goes to Jeff, who really doesn't want it. The ivory headpiece is later worn by Troy in his and Abed's apartment, indicating Jeff gave it to them instead.
