History Series / BrooklynNineNine

** Also Terry, who despite looking like a ScaryBlackMan, is actually a huge nerd. He enjoys fantasy books in particular, and used to dress up as a superhero when he was a kid. It's also discovered in a Season 4 episode that he secretly writes fanfiction in his spare time.

** CanadaEh is often brought up, either as a nice place, but more likely as the butt of jokes. Nine-Nine people just can't help themselves and snark at how unspeakably nice and safe or boring and useless Canada is compared to Brooklyn.

* StudioEpisode: In "Serve & Protect", Jake and Rosa are assigned to solve a case on the set of their favorite crime show, ''Serve & Protect'', with Jake struggling to solve the case objectively since he is so starstruck. The episode pokes fun at some of the inaccuracies of crime shows, such as actors not wearing gloves when handling evidence, [[spoiler: though this turns out to be a ruse since the actor in question was the culprit pretending to be a bad MethodActor.]] Jake also gets a character named after him... a gross, perverted serial killer, as revenge for him accusing the producer of the theft (but [[ComicallyMissingThePoint he is just happy they used his name at all]]). As a meta bonus, the lead actor on ''Serve & Protect'' is played by Creator/NathanFillion, who was best known for the long-running crime show ''Series/{{Castle}}'' at the time this aired.

** Played for laughs when Rosa meets Marshawn Lynch (AsHimself), whom she idolizes for his tight-lipped media appearances, only for him to be a MotorMouth

*** Jake and Terry's second meeting with the fantasy author goes even worse than the first.
*** Jake and Rosa are overjoyed to work for Hawkins, a legendary cop who they both idolize. Then, they find out she is actually corrupt as hell. [[spoiler:And ''then,'' she frames them both for her crimes and has them sent to jail.]]

** Season 8: Jake meets his former sergeant after years only to find out that she is now corrupt.

* BrokenPedestal: Somewhat of a [[RecurringElement recurring theme]] in the series. Chances are, if a main character meets someone they admire, this trope will come into effect by the end of the episode or story arc.
** Jimmy Brogan, once idolized by Peralta as a HardboiledDetective writer straight out of the '70s, [[DeliberateValuesDissonance turns out to be a racist, misogynistic homophobe straight out of the '70s.]]
** Likewise Peralta's father, whom Peralta worships and whose personal failures and poor parenting he constantly excuses--until he realizes that he actually isn't a very good father.
** After boasting of a "major celebrity" in trouble, Holt reveals it's actually an oboe player no one knows about but he idolizes. He takes the lead on the case to find his stolen oboe with Boyle in tow, gushing over the oboist, who lives in a crummy apartment with little money. It turns out the player staged the robbery to sell the oboe and collect the insurance money ("because oboists are not celebrities") and Holt is stunned his idol could be this way.

** Terry is gets put on a case where his favorite fantasy author is given a threatening note. He has been a fan of the man for years and kept a letter written back to him which inspired Terry to become a cop. During the investigation, he and Jake discover the handwriting on the note matches the author's. Confronted, the author admits that he's been using an assistant to write the "thank you" letters as he has no time to worry about what every fan thinks of him. Terry is naturally jarred at how much of a jerk the author is but Jake insists Terry is a better cop than the author is a writer.
** Jake and Rosa are overjoyed to work for Hawkins, a legendary cop who they both idolize. Then they find out she's actually corrupt as hell. [[spoiler:And ''then'' she frames them both for robbery and has them sent to jail.]]
** Amy has long boasted of how much she loves filing paperwork and sees it as a perfect system. When she has to obtain a permit for a case, she finally realizes how much of a mess the bureaucracy is why everyone else hates it. During the case, Amy is happy to meet the woman who created the forms (and many of her other favorites), boasting of her as a "legend." She discovers that not only is the woman a CrazyCatLady but her "system" was just a mix of incompetence, spite and dyslexia.
** Played for laughs when Rosa meets Marshawn Lynch (AsHimself), who she idolizes for his tight-lipped media appearances, only for him to be a MotorMouth

** The corrupt cop/prison arc begins in the final episodes of Season 4 and concludes in the second episode of Season 5, although its ramifications are felt through Season 5 as the Nine-Nine are moved to the night shift.

* EveryoneHasStandards: Kevin is portrayed every bit as stoic and reserved as Holt but there's his reaction to Holt's attempts to help coach Rosa through a break-up.
--->'''Holt:''' I brought it up with Kevin, and he said we're quote "both sociopaths" unquote.

** In "[[Recap/BrooklynNineNineS5E14TheBox The Box]]", Peralta has only 8 minutes to get a confession before the murderer, a highly intelligent but arrogant man, walks. Peralta describes the crime and how he got lucky "at every turn". The murderer gets angrier and angrier before finally snapping and describing how every piece of the murders was intelligent and preplanned. All he had to do to stay free was to ignore Peralta's needling and insults for 8 minutes.
