[[caption-width-right:320:This year will be more normal than the previous two, as explained by [[HypocriticalHumor the opening musical number.]]]]

[[CrowdSong And be less weird]]\\
[[BigLippedAlligatorMoment Than the first two years combined!]]''

Pierce tries to rejoin the group, only to be edged out by Jeff when he claims that their friendship has evolved beyond needing to be in the same class. In reality, though, he only wants Pierce gone, and when he gets kicked out of the biology class it sends him panicking.

Chang's been trying to live in the air ducts, though Troy has convinced Dean Pelton that it's just Annie's Boobs the monkey, causing him to get the ducts gassed.

The Dean, meanwhile, wants no more of the ''NationalLampoon''ery that's been going on the past two years and tries to take a more active administrative role, starting by chastising the Dean of Greendale's Air Conditioning Repair Annex for purchasing a new coffee machine. However, his efforts to crack down reveal that not only does the Annex have a higher rate of graduate employment, 80% of Greendale's funds come from it. The Vice-Dean subsequently gets the Annex split off, leaving Greendale virtually bankrupt. The security guards quit and Chang becomes their replacement, working for room and board.

In a third, smaller subplot, Britta tries to help Abed cope with ''Series/CougarTown'''s premiere getting bumped to January by hooking him on British shows. Her successful efforts lead her to decide to major in psychology and become a therapist.

! The ''Series/{{Community}}'' episode "Biology 101" provides examples of:

* AnalogyBackfire: Paradoxed. Britta actively shows how well she ruins things by ruining Troy's Ruining Club analogy, [[LogicBomb thus, proving his point.]]
%%* AxCrazy: Jeff, literally for both criteria.
* BadassBeard: The Dean tries one out, and it doesn't turn out very well.
* BadassBoast:
-->'''Vice-Dean Robert Laybourne:''' You could have lived the rest of your life in ignorance and died a happy pansexual imp. But you wanted to feel power this year. Well, now you are going to feel ''my'' power, as it surges downward from me straight through you from nostril to rectum now until the end of time. And ''that's'' "[[IronicEcho wassup]]".\\
'''Dean Pelton:''' ''[Panicking]'' ...I forgot everything you said before 'rectum'!
* BritishBrevity: [[DiscussedTrope Discussed.]]
* CallBack:
** [[Recap/CommunityS2E21ParadigmsOfHumanMemory Six seasons and a movie!]]
** [[Recap/CommunityS2E11AbedsUncontrollableChristmas Abed becomes catatonic]] when incredibly stressed.
** Jeff's character arc essentially is a mini-version of the "Pierce acts like a jerk and gets excluded by the group" arc from Season 2.
* CaptainErsatz: ''Inspector Spacetime'' is a transparent riff off of ''Series/DoctorWho''.
* CliffhangerCopout: The second season ended with Pierce declaring he was done with the study group and walking out on them, leaving audiences to wonder what this would mean in the next season. The resolution is... Pierce walking into the study room, explaining he'd changed his mind, and asking them to take him back. Probably deliberate, since it was never likely that Pierce would be gone from the group for good.
** It could also be a subtle inversion of the previous season's opener -- there, a lot of angst and complicated feelings unravelled as a result of the events of the season 1 finale. In this case, everyone spends the first few minutes of the episode fretting about the possible problems and lingering implications of the previous season finale ... and it's all more-or-less sorted out in five minutes.
* CrowdSong: The opening.
* CurseCutShort: Jeff's PrecisionFStrike doesn't ''quiiite'' make it out.
* DiggingYourselfDeeper: Jeff's frantic attempts to explain his various rationales for the MistakenForRacist example and why that doesn't make him a racist only serve to make him look more racist.
* DisproportionateRetribution: The Dean, trying to be a better dean, inquires why Vice-Dean Laybourne didn't consult him on the Air Conditioning Repair School Annex' purchase of a new espresso machine. Laybourne, in response, reveals that the repair school makes 80% of Greendale's budget, and that they will now separate from the rest of Greendale leaving them broke, and [[ArsonMurderAndJaywalking hires a barber to shave the Dean's goatee off.]]
* DownerEnding: Cougarton Abbey. Doubles as BlackComedy.
* DreamSequence: Jeff's kicks off the episode.
** And then he gets another one after being knocked out by the monkey knockout gas.
* DrunkWithPower: As part of his drive to eliminate the "{{National Lampoon}}ery", the Dean starts throwing his weight around. Unfortunately, this antagonizes the Vice-Dean of the Air Conditioning Repair Annex... who, as it turns out, is considerably more powerful.
* DuelingShows[[invoked]]: Fictional example, ''Series/DoctorWho'' vs. Inspector Spacetime. WordOfGod [[http://twitter.com/#!/danharmon/status/117571958182383616 is that Doctor Who is a ripoff of Inspector Spacetime]].
** Given that Inspector Spacetime supposedly started the year before Doctor Who did, this is apparently true.
* EasilyForgiven: Part of the CliffhangerCopout. Pierce is automatically forgiven by everyone (except Jeff) for all of his evil actions last season. Pierce also forgives the study group rather easily for alienating him.
* EatingLunchAlone: Leonard is quick to call out Jeff on this.
* EvenEvilHasStandards: Even Pierce seems to think that Jeff implying that "all black people are in prison" is going too far.
* FloweryInsults:
-->'''Troy:''' You are human tennis elbow. You are a pizza burn on the roof of the world's mouth. You are the opposite of Franchise/{{Batman}}.
* FunnyBackgroundEvent: More of an ''un''funny background event; several students can be seen walking across campus normally in the background of Jeff's musical fantasy.
* GeniusBruiser: Professor Kane got his [=PhD=] from 6,205 hours of reading books from a library... in prison. [[{{Determinator}} One hour per day.]]
** For the record, that's 17 years.
* GettingCrapPastTheRadar:
-->'''Dean Pelton:''' Brainstorm. Idea shower. Spray your solutions all over me.
** And later:
-->'''Vice Dean Laybourne:''' Tell you what, you bring your head down to my appendage tomorrow, and I'll show you [[SomethingElseAlsoRises what's up.]]
* HeroicBSOD: Abed nearly has one when he discovers ''Series/{{Cougartown}}'''s been moved to midseason and has a full one when ''Cougarton Abbey'' ends at [[BritishBrevity six episodes]] with a [[BlackComedy mass suicide]].
* HopeSproutsEternal: Prof. Kane discusses how seeing a single blade of grass growing out of a crack in his cell got him through his sentence.
* HypocriticalHumor: Jeff, having just [[AxCrazy attacked the study room table with an axe screaming about how he's going to kill it because it controls their lives]], on Dean Pelton:
-->'''Jeff:''' What is ''with'' that guy? ''[does 'crazy' motion with his finger]''
** A meta-example; the show essentially announces that it's going to dial back the zany weirdness a bit from the previous years... by having the characters launch into a big, flashy song-and-dance musical number about how they're going to dial back the zany weirdness a bit.
** Pierce getting shocked when Jeff appears to be racist.
** Starburns telling Jeff to learn to blend in.
* ImagineSpot: Jeff gets one. It's a musical number. [[LyricalDissonance About how much less zany this year will be.]]
* IronicEcho:
** When throwing his weight around to Vice-Dean Laybourne, the Dean demands to know 'wassup'. Later, upon being confronted with the true power of the Air-Conditioning Repair Annex, the Dean is informed in no uncertain terms by Laybourne precisely 'wassup', and ''he's'' a lot more intimidating.
** Having spent the previous season being one of the primary movers behind excluding Pierce / trying to get him kicked out of the group, Jeff ends up spending most of the episode being excluded / threatened with being kicked out of the group in much the same way as Pierce was.
* {{Irony}}: Jeff's dream shows just how much he wants everything to be more "calm and normal". But in this episode, it's mainly him disrupting the calm and bringing the crazy.
* IWantSong: ''We're gonna get more calm and normal! We're gonna fix our state of mind!''
* LargeHam: Chang is seen carrying an actual large ham, for no apparent reason other than to lampshade that he ''is'' one.
* {{Metaphorgotten}}: The Dean has put a ''lot'' of thought into what he'd do if he was running a monkey hotel.
* MistakenForRacist: The study group thinks Jeff thinks all black people look alike after he sees a picture of Pierce and Sugar Cube in Kane's office and assuming that it depicts Kane. He saw it from a distance! He saw the prison jumpsuit!
* NiceJobBreakingItHero: Abed was in a funk to begin after learning ''Series/CougarTown'' wouldn't premier until midseason, but he was still functioning. Britta's intervention puts him into a complete catatonic state.
* NotSoDifferent: Jeff and Pierce. Jeff's breakdown over the episode is a mini-version of the character arc Pierce underwent over the previous season, and he begins to be ostracised from the group for the same reasons they ostracised Pierce.
* OffscreenTeleportation
--> '''Pierce:''' I'm back.
* PantyShot: In the opening song Alison Brie's skirt flutters a little ''too'' high during some of her twirls.
* PetTheDog: Pierce's lie about bribing the teacher to kick Jeff out of class. May border on a HeroicSacrifice, considering that Pierce sacrificed his rarely-achieved moral high ground in order to redeem Jeff in the group's eyes.
** Made even more heroic when you consider that of all the members of the study group, Jeff was the most antagonistic against him, especially in this episode.
* PrecisionFStrike: ''Averted''. A furious Jeff cuts himself off ''right'' before he tells Pierce to "shut the ____ up".
* PromotedToOpeningCredits: Jim Rash (Dean Pelton) is added to the opening credits starting with this episode.
* RainbowMotif: The last scene of the episode provides a blink and you'll miss example. Each member of the study group is wearing a particular color motif, that clockwise around the table goes increases up the specturm. The specific colors involved are [[color:grey:grey]] (Jeff), [[color:purple:violet]] (Annie), [[color:blue:blue]] (Shirley), [[color:green:green]] (Pierce), [[color:gold:yellow]] (Troy), [[color:orange:orange]] (Abed), and [[color:red:red]] (Britta).
* TheReasonYouSuckSpeech: Britta gets one from Troy when she sends Abed into his HeroicBSOD: "You are human tennis elbow. You are a pizza burn on the roof of the world's mouth. You are the opposite of Batman."
* RedHerringTwist: Pierce's departure last season doesn't last.
* RuleOfSymbolism: Jeff gets a monkey knock-out gas-fueled dream where he [[RapidAging rapidly ages]] [[NotSoDifferent into Pierce]], reaching for the study-room table like a Monolith.
* ScrewTheMoneyIHaveRules: As Jeff says, Professor Kane never took a bribe in his life.
* SeriousBusiness: The fact that ''Series/{{Cougartown}}'' is delayed to mid-season nearly provokes a mental breakdown in Abed. The fact that its [[TransAtlanticEquivalent British counterpart]] [[BritishBrevity only lasted six episodes]] sends him into a catatonic state.
* ShipTease: The biggest one would be Jeff/Annie, but Abed/Annie, and Abed/Britta are also hinted at.
** Abed/Troy also gets a pretty big spotlight (see the HoYay entry).
** A subtle one during the joke where it sounds like Troy and Abed are coming out. One might expect Britta to be overjoyed to have gay friends, but she looks directly at Troy with an expression of confusion, fear and hurt. When it turns out they're just gonna be roommates, she seems relieved.
* ShoutOut:
** The name ''[[Series/{{Cougartown}} Cougarton Abbey]]'' is one for ''Series/DowntonAbbey''.
** [[KillEmAll The ending of]] ''[[Series/{{Cougartown}} Cougarton Abbey]]'' is one to ''Series/{{Blackadder}}''
*** As well as the end of ''Series/BlakesSeven''
** ''[[JustForFun/InspectorSpacetime Inspector Spacetime]]'' is one to ''Series/DoctorWho''.
** In Jeff's psychotropic-induced meltdown is one for the ending of ''Film/TwoThousandOneASpaceOdyssey'', the upright study-room table as the TheMonolith .
** The opening song-and-dance number is not dissimilar to those which appear on ''Series/{{Glee}}'' or ''Film/HighSchoolMusical''.
*** Speaking of, at one point Troy, Abed, Jeff, Annie and Britta strike a pose suspiciously similar to the final one from [[LightNovel/HaruhiSuzumiya the "Hare Hare Yukai" dance]].
** At the end of the episode, Starburns gets himself kicked out of biology when he asks Professor Kane if being a drug dealer and professor, respectively, meant they could get a ''Series/BreakingBad'' thing going on.
** "I know who Sean Penn is! I've seen ''Film/{{Milk}}''!"
** [[Film/TheShining At the end, as Jeff destroys the table.]]
* StatusQuoIsGod: Lampshaded, Jeff and Dean Pelton both think things are going to change a lot this year, only to be proven quite wrong.
* SternTeacher: Prof. Kane is presented as one.
* StylisticSuck: ''Inspector Spacetime'' somehow manages to look even cheaper than ''Series/DoctorWho'' ever could even on it's lowest budgets.
* {{Subject 101}}: Biology 101
* SuicideAsComedy: [[KillEmAll The ending of]] ''[[Series/{{Cougartown}} Cougarton Abbey]]''.
* TheManBehindTheMan: Turns out, Greendale's Air-Conditioning Repair Annex is where practically Greendale's entire budget comes from, and Vice-Dean Robert Laybourne has ''far'' more power and clout than Dean Pelton. As Dean Pelton unfortunately discovers.
* TemptingFate: Saying out loud that Pierce would never be coming back.
* TookALevelInJerkAss: Jeff towards Pierce.
* TookALevelInKindness: After spending much of the previous season as a borderline villain, Pierce enters this episode having adopted a more "bumbling but well-meaning" personality.
* TransAtlanticEquivalent: ''Cougar Town'' and ''Cougarton Abbey''.
* UpUpAndAway: Opening Shot.
* VillainousBreakdown: Jeff, who takes over Pierce's normal role as the group 'villain' upon losing his place in the biology class, ends up attacking the study room table with a fireaxe. Pierce even lampshades it when he lies to the group to enable Jeff to be redeemed at his expense:
-->'''Pierce:''' I lied. But you seemed to have a worse time being the bad guy than me.
* VisualPun: Prof. Kane tells a story about being in prison and being inspired by seeing a blade of grass growing out of a crack in his cell, then compares Jeff's cell phone and "too-cool-for-school attitude" to a concrete block. Later, we see that Jeff sends him a cellphone with a plant sprouting out of the keyboard on his desk.
