An April Fools Day pranks goes wrong, and newly deputized campus security officers Shirley and Annie are on the case. Meanwhile, Jeff and Troy take advantage of Pierce's idiosyncratic beliefs about becoming a "level six laser lotus" in his "Buddhist" chapter to play a prank of their own.

!!The ''Series/{{Community}}'' episode "The Science of Illusion" provides examples of:

* AprilFoolsPlot: Britta's attempt at a prank, in order to escape the label of "buzzkill".
* BackhandedCompliment: Jeff's initial attempts to try and make Britta feel better during her meltdown at the end fall squarely into this trope.
* BewareTheNiceOnes: Annie and Shirley compete for the role of the [[GoodCopBadCop Bad Cop.]] It doesn't end well.
** UpToEleven when Annie starts slamming Jeff's head into the study hall table.
* ByTheBookCop[=/=]CowboyCop: Both Shirley and Annie compete to be recognized as the latter, despite both usually being closer to the former in temperament.
* BuddyCopShow: Parodied with Annie and Shirley, campus security guards. Abed, who is following them around, ends up invoking a whole load of tropes surrounding this.
* CallBack
** In the opening scene, an "Enviro-dale" flyer can be seen on the wall as Leonard sneaks up on the Dean.
** "Abed, how fast can you run to the theater department?"
** "I am now a level 6 laser lotus."
* CatchPhrase: First appearance of "Troy and Abed in the morrrning" in the tag
* ChekhovsGunman: Two elderly students vandalizing the Dean's secretary's desk bear resemblance to the "Hipsters" of "Messianic Myths and Ancient Peoples".
* ChurchOfHappyology: Yet more confirmation in this episode that Pierce's "Buddhist" church is somewhere between this, a {{Cult}} and a ''TabletopGame/DungeonsAndDragons'' character build:
-->'''Annie:''' So, what happens at level six?\\
'''Pierce:''' Well, no one in my hive has ever seen a Six, but from what I hear I have immunity to germs, heightened psychic ability, increased night vision...\\
'''Troy:''' [[SarcasmMode Any bonuses to your combat score?]]\\
'''Pierce:''' [[SarcasmBlind I assume I'll fight better if I can see more.]] [[HypocriticalHumor Dumbass.]]
* ComplimentBackfire: Britta clearly isn't very impressed when Jeff's initial attempts to make her feel better during the meltdown at the end lead him to describe her as "the anti-Winger" and "the dark cloud that unites us".
* ContinuityNod: Pierce's napkin drawing of the Greendale Human Being can be seen hanging up behind Dean Pelton's desk.
* CovertPervert: Shirley takes the opportunity while "frisking" Jeff to cop a feel of his chest.
* DaChief: Abed performs a pitch perfect demonstration for the dean, who is technically the actual chief.
* DepartmentOfRedundancyDepartment: Shirley and Annie's attempts to one-up each other see them occasionally do this.
-->'''Annie:''' Looks like we've got enough tiny items to equip an amphibious mariachi band!\\
'''Shirley:''' Of frogs!
* {{Frameup}}: Britta frames up Jeff as the one who tried to make the prank.
* GoodCopBadCop: Annie and Shirley can't quite keep this straight between them.
* GroupHug
* ItsAllAboutMe: Very subtly done; when trying to make Britta feel better at the end, Jeff's very first thought is to raise an unflattering comparison with himself ("You're the ''Anti-''Winger!").
* JackBauerInterrogationTechnique: Annie slams Jeff's head down onto a table in an attempt to do this, but given the context of the show (and the general cuteness of her character), it comes off more as TortureForFunAndInformation (at least to the audience).
** Shirley then provides a straighter example as she threatens to cut Jeff up with a pizza slicer.
* {{Jerkass}}: It's subtle, but clearly noted that Jeff's "trademark gift for levity" seems to primarily revolve around either snide comments about other people or making fun of them by making them look stupid.
-->'''Britta:''' Oh wait -- I forgot. It's not your kind of joke; it's not at anyone's expense.
* KickMePrank: Leonard does this to the Dean.
* MoralityPet: Invoked. The cadaver accidentally tossed out a window had a mother. She's brought in by the Dean to read from his journal.
* OddCouple: She's a seriously cute recovering teen drug addict. She's a newly-single, single-mindedly Christian housewife and mother. [[TheyFightCrime They Fight Crime (sort of)!]]
* OnlySaneMan: Jeff starts to mention that he and Abed are this before Abed cuts him off.
* PassThePopcorn: Abed tags along Annie and Shirley's buddy cop escapades with [[strike:a box of Raisinettes]] [[BrandX chocolate raisins in a non-descript yellow box]]. (He ends up giving the rest to a stranger to save his seat... which is the back seat of Shirley and Annie's mobile security guard cart.)
** Abed is usually eating something in every scene of this episode, and in fact it's likely you'll see him doing it in prior episodes as well.
** When he steps up to an active role, Abed passes the popcorn off to the Dean.
** Right at the end he can be seen feeding some to (a handcuffed) Jeff as they watch the rest of the group together.
* RedBaron: Annie has several (Annie Adderall being one) and attempts to use them as an intimidating introduction:
-->'''Annie:''' Morning boys, Iím Annie Edison but people call me Psycho because I had a nervous breakdown in high school.
* SaltAndPepper
* ShoutOut: Jeff, to Shirley and Annie. "[[Series/CagneyAndLacey Cagney... Lacey]]."
** Thanks to Abed: "[[Film/LethalWeapon I'm too old for this!]]"
** In-universe, when Jeff and co. dress Pierce as the Cookie Crisp Wizard, complete with wand.
* StopOrIWillShoot: Parodied; Annie learns the hard way that this doesn't work when all you have is a pepper spray... and that when you try 'shooting' the fleeing suspect, all you end up doing is running straight into a cloud of pepper spray.
%%* TheyFightCrime:
* TurnInYourBadge: Invoked by Abed, and totally deserved.
* UnwantedAssistance: [[InvokedTrope The Dean has a moment of this]] when even ''he'' realizes how overboard Abed invoking BuddyCopShow tropes is getting after Abed feeds him the line "I just got off the phone with the Mayor!" as he's dressing down Annie & Shirley over failing to catch the culprit.
* VillainousBreakdown: For a given value of 'villain', at least (she's the one behind the prank that ends up causing all the trouble, and thus the 'criminal' to Annie and Shirley's 'cops' in this episode), when Britta reveals that she was the one behind the prank her MotiveRant ends up with her bursting into tears over being a killjoy. It then leads to a chain reaction of weepy confessions of inadequacy from Annie, Shirley, Pierce and Troy.
* WhereEverybodyKnowsYourFlame: When Pierce tries to read Jeff's mind, he sees a "dark nightclub" with "throbbing music".
** And "Penises!"
* YouAreNotAlone: Played for (slightly bittersweet) laughs; when Britta starts crying about how insecure she feels over being the group killjoy, Annie tries to comfort her by saying that she feels insecure because no one takes her seriously due to her age... only to then start crying ''herself'', which then prompts a chain reaction of weepy confessions from Shirley over her insecurity over her age, Pierce over not becoming a [[ChurchOfHappyology level six Laser Lotus at his "Buddhist" church]] and Troy crying because [[ItMakesSenseInContext he doesn't know who the Cookie Crisp Wizard is]].
* YourMakeupIsRunning: After Annie pepper sprays herself, the scene eventually jump cuts to her picking up her hat with her mascara running down her eyes.
* YourMom: Jeff's response to interrogation is that he was at a bar. With Shirley's Mom. Shirley's not happy, but it backfires big-time on Jeff when Annie takes it as a prompt to slam his head into the study room table.
