* ArchivePanic: Going for a solid 12 seasons and about 265 episodes puts the show in this category, to say nothing of the four spinoff movies and the novel series that (as of 2014) numbers somewhere in the 40s and is still going at a rate of two new books a year.
* AwardSnub: Angela Lansbury: 12 Years, 12 Emmy nominations, not a single win.
* CrossoverShip: Nearly a canon example. The end of the ''Series/MagnumPI'' crossover teased Jonathan Higgins and Jessica, although it never went past Higgins quite obviously crushing on Jessica, to her amusement.
** It was also added to at the end of the syndicated version of the first part, "Novel Connection".
* EarWorm: The famous [[http://www.youtube.com/watch?v=2BfbDEYY6t4 theme song.]]
* HilariousInHindsight: "It's a Dog's Life": Cherie Currie's character is named Echo. [[http://www.poplifeart.com/cherie_currie1.jpg Guess what brand of power tools Currie endorses as a chainsaw artist?]]
** In "It Runs In the Family", Emma [=McGill=], also played by Lansbury, laughs off returning to singing because her voice has "... more cracks than [[Disney/BeautyAndTheBeast an old teapot."]]
** Jessica's full name is Jessica Beatrice Fletcher. She's involved in murder mysteries. [[VisualNovel/UminekoWhenTheyCry Guess who else is named Beatrice and involved in murder mysteries?]]
* {{Narm}}: The infamous drive-by swording sequence from "The Celtic Riddle".
* NarrowedItDownToTheGuyIRecognize: Occasionally subverted. In fact, many guest stars turned out to be allies of Jessica's or a RedHerring, while a character played by a much less famous person was the actual killer.
** Played straight in "A Very Good Year For Murder", where [[spoiler:the family patriarch played by Eli Wallach]] was the murderer.
* OccamsRazor: One case has a nasty version of this [[spoiler: until you realize that the woman who made this 'mistake' is that episode's perp and is shifting blame away from herself. Before TheReveal it's just jarring.]] Basically, Jessica returns home to have her phone ringing but it disconnects before she can answer it. Soon after, she's subpoenaed to appear in front of a federal court over the disappearance of a person she doesn't know. Does the persecutor just accept that Jessica doesn't know who it is and that it's a mis-dialed number [[spoiler: as Jessica finds out while snooping around the victim's office?]] No, she charges Jessica with contempt of court and has her thrown in jail for a night. [[spoiler: Even if she was just trying to frame someone else, if the persecutor had just gone along and admitted that it was a mis-dialed phone number rather than haul Jessica to the witness stand, she would've gotten away with it.]]
* RetroactiveRecognition: Kathryn Morris was in one of the TV movies three years before ''Series/ColdCase'' premiered.
** George Clooney and Julianna Marguiles both appeared in episodes (separately) eons before {{ER}} made them famous.
* [[HeReallyCanAct She Really Can Act]]: Lois Chiles, considered by critics to be a rather flat presence in films like ''[[Film/{{Moonraker}} Moonraker]]'' and ''Literature/DeathOnTheNile'', improves considerably in "The Return of Preston Giles", so much so that when she [[spoiler: fatally shoots Giles]] at the episode's end, she's almost chilling.
* TheScrappy:
** Dorian in [[ClicheStorm "Night of the Headless Horseman"]]. He brings Jessica over so she can pose as his mother and does several stupid things no human being should ever do in his position under any circumstance- like trying to score a relationship with his crush, Sarah, who just so happens to be the daughter of [[{{Jerkass}} a snobbish, stuck up man only concerned with "pedigree" and being high class]]. [[BadBoss Oh, and he's Dorian's boss.]] Dorian is also an [[ThisLoserIsYou extremely unlikeable caricature of the typical, orphaned loser nerd]] that can't speak his mind out and attends a prestigious school.
** ''No one in this galaxy'' likes Marty from "Showdown in Saskatchewan."
* XMeetsY: ''Literature/MissMarple'' meets ''Series/{{Castle}}''.
