* ActorAllusion:
** One of the many, '''many''' people who have taken the court hostage over the years was a woman with a grenade who couldn't distinguish television shows from reality. She was played by Marion Ross, aka [[Series/HappyDays Mrs. Cunningham]]. She lists her many friends which were fictional TV characters and it included "The Fonz".
** Another episode had Dan being held hostage by an insane woman who acts out scenes from horror movies. When the TV announces that ''Film/TheTexasChainSawMassacre1974'' is about to begin, he says, "Seen that already." John Larroquette was the narrator for the [[Film/TheTexasChainSawMassacre1974 original film]], [[Film/TheTexasChainSawMassacre2003 2003 remake]], and the ending of the [[Film/TheTexasChainsawMassacreTheBeginning prequel to the latter]].
* [[AuthorExistenceFailure Actor Existence Failure]]: Selma Diamond after the second season, and Florence Halop after the third. Marsha Warfield was hired because she was much younger, so this could be prevented from happening a third time.
* TheCharacterDiedWithHim: When Selma Diamond and then Florence Halop died, their respective characters were written as having passed away too.
* ColbertBump: Mel Tormé's guest appearances introduced him to a whole new audience who otherwise would have never heard of him and he developed a following among Generation Xers.
* TheDanza:
** Selma Hacker/Selma Diamond, and Florence Kleiner/Florence Halop.
** Could also be invoked for Mac Robinson/Charles Robinson.
** Averted with Harry Stone played by Harry Anderson, oddly enough. According to series creator and executive producer Reinhold Weege's DVD commentary, the character was called Harry and was a devoted Tormé fan and magician before magician turned actor Harry Anderson auditioned.
** Yakov Smirnoff's occasional guest appearances as Yakov Korolenko.
** William Utay as Will, the EvilTwin of homeless guy Phil.
* DawsonCasting: Don Cheadle plays a robber in one episode. The character was supposed to be 16, Cheadle was 24 at the time.
* DirectedByCastMember: Several.
** John Larroquette directed 2 episodes.
** Harry Anderson directed 2 episodes. He also wrote 5 of them. (One - "Caught Red Handed" from the fourth season - he both wrote ''and'' directed).
** Charles Robinson directed 3 episodes.
* KeepCirculatingTheTapes: Warner began issuing [=DVDs=] of the show in 2005. It took eight years for them to release the entire series and even then most of the seasons are only available as [[VanillaEdition no-frills]], "manufactured-on-demand" releases available only online. Shameful considering ''Night Court'' was part of NBC's vaunted '80s Thursday Night Line-Up, along with ''Series/TheCosbyShow'', ''Series/ADifferentWorld'', ''Series/FamilyTies'', ''Series/{{Cheers}}'', ''Series/{{Wings}}'', ''Series/HillStreetBlues'', and ''Series/LALaw''.
* TheOtherDarrin: Phil Sanders was played by a different actor (Blackie Dammett, Anthony Kiedis' father) when he first appears and is more snarky than deferential towards Dan.
* RealitySubtext: "Flo's Retirement" was a fitting sendoff for Florence Halop, who was dying of breast cancer. And she ''still'' managed to finish out the season.
* TechnologyMarchesOn: Averted, Dan makes use of a cell phone several times, Harry owns several laptop computers And Mac eventually trades in his beloved files for a computer as the series goes on.
* UnintentionalPeriodPiece: The show is very much based on the [[TheBigRottenApple pre-Giuliani NYC]].
