* ActorAllusion: A strange case. For a while, Carla's ex-husband Nick was TheFaceless, and was described as [=Danny DeVito=]. Rhea Perlman played Zena, [=Louis DePalma's=] girlfriend on ''Series/{{Taxi}}''. [=DeVito=] was going to play Nick, but his movie career took off and Dan Hedaya was hired to play the role instead.
* AdoredByTheNetwork: When ''Cheers'' finally went off the air on May 20, 1993, Creator/{{NBC}} dedicated a whole night to the show's final episode. The night began with a "pregame" show hosted by NBC sportscaster Bob Costas, followed by the final 98-minute episode itself. NBC stations, O&Os and affiliates alike, then aired tributes to ''Cheers'' during their local newscasts, and the night concluded with a special edition of ''Series/TheTonightShow'' broadcast live from the Bull & Finch Pub.
** The tributes didn't end there. On the following day's ''Series/{{Today}}'' broadcast, the show dedicated an almost ten-minute segment documenting how loved the show was to people, with ''Today'' anchor Katie Couric being seen briefly on the ''Cheers'' set. The segment began with the show documenting the ''Tonight Show'' broadcast with brief comments from the show's cast, in addition to recapping the finale. The show then did an on location report in which NBC News correspondent Roger O'Neil went on location to actual bars across the country, in which staff and patrons of those bars reflected on watching the program from those exact bars. After that, the segment concluded with Couric, now back at NBC News world headquarters in New York, sitting down for an interview with then NBC Entertainment president Warren Littlefield, speaking from the Bull & Finch, about what shows he was going to use to fill the void, along with a side interview with Jeannie Park, then senior editor for television at ''Entertainment Weekly'', in which she and Couric discussed the phenomenon of how ''Cheers'' was able to run for 11 seasons despite having abysmal ratings on its inaugural season.
** So adored that the show was an utter bomb in its first year, having the ''worst'' Neilsen ratings of the year. Fortunately, NBC Entertainment president Brandon Tartikoff refused to cancel it, and put it in a prime slot right after ''Series/TheCosbyShow'' and ''Series/FamilyTies'', and soon became the #1 sitcom in America, even beating its lead-ins. Ironically, Tartikoff would later serve as chairman of Creator/{{Paramount}}, which produced both ''Cheers'' and ''Family Ties''.
* TheCharacterDiedWithHim: Nicholas Colasanto/Coach Ernie Pantuso.
* TheDanza: Woody Harrelson played Woody Boyd.
** Oddly enough, the character was named Woody before Harrelson got the part.
** All of the minor barflies, such as Paul (Paul Wilson), Al (Al Rosen), Pete (Peter Schreiner), Alan (Alan Koss), Tim (Tim Cunningham), Steve (Steve Giannelli), Phil (Philip Perlman, Rhea's father), Hugh (Hugh [=McGuire=]), Tom (Thomas Babson), Larry (Larry Harpel), Paul (Paul Vaughn) Tony (Tony [=DiBenedetto=]), and Mark (Mark Arnott).
** A few of the recurring characters in the show's early run...including a pre-''Series/NightCourt'' [[HeyItsThatGuy Harry Anderson]] as itinerant ConMan "Harry the Hat".
*** Lampshaded when Woody won the lead in ''Theatre/OurTown'' and remarked that his co-star was named Emily (same as her character), so she wouldn't have to worry about difficult things like responding to a new name.
* DirectedByCastMember: Four episodes by John Ratzenberger and one by George Wendt in later seasons.
* HeAlsoDid: Roger Rees plays Robin Colcord in this series, Lord John Marbury on ''TheWestWing,'' and the Sheriff of Rottingham in Film/RobinHoodMenInTights.
* IronyAsSheIsCast: Lilith Sternin was initially depicted as a terrible singer, even though before ''Cheers'' Creator/BebeNeuwirth was mostly known for her singing roles in Broadway musicals; in 1986 she even won a Tony Award for a production of ''Theatre/SweetCharity''. Later on the writers had Lilith take some singing lessons, and all of a sudden she became [[TheCastShowoff a great singer]].
* OldShame: Diane has many, from PokeThePoodle incidents ("I'll never forget the day I brought home a ''[[DirtyCommunists utopian socialist]]''. Unbelievable--I know! Unbelievable. I was a rebel, then....") to her skill at bowling, which she fears would threaten her "refined" image ("If you utter a ''word'' of this to ''anyone'' who matters, I will ''find'' you--and kill you.").
* RealLifeRelative: Kelsey Grammer's daughter Spencer had an uncredited role in "One Hugs, the Other Doesn't".
** Phil the barfly was played by Phil Perlman, Rhea Perlman's father. In addition, Rhea's sister, Heide Perlman, was a frequent writer.
** Vera Petersen is Bernadette Birkett, [[CastingGag George Wendt's wife]].
* LifeImitatesArt: ''Series/{{Jeopardy}}'' uses "pulling a Clavin" to refer to when a contestant whiffs the way Cliff did on an episode.
* TheOtherDarrin: Two different actors played Gary in the various "Bar Wars" episodes.
* RealLifeRelative: Whenever Norm's wife is heard [[spoiler:and her brief on-screen appearance]], she was played by George Wendt's wife.
* RecycledScript: Not only is the storyline of the Season 11 episode "Norm's Big Audit" virtually identical to that of the ''Series/{{Wings}}'' episode "Hell Hath No Fury Like a Police Woman Scorned," but the same actress who played the hard-nosed, lovesick policewoman in ''Wings'' was hired to play the hard-nosed, lovesick IRS auditor in this series.
* StarMakingRole: True for almost the whole cast, except for Kirstie Alley who got her big break a few years earlier with ''Film/StarTrekIITheWrathOfKhan'', and arguably Bebe Neuwirth with her stage experience. Most dramatically true for Woody Harrelson, who went on to a very successful film career.
* ThrowItIn: According to John Ratzenberger, he badly botched his audition for the role of Norm, and, figuring he had nothing to lose, asked if the cast included a bar [[KnowNothingKnowItAll know-it-all]]. He proceeded to improvise for a few minutes as such a character, and the writers subsequently created the part of Cliff for him.
** Actually, [[{{Pun}} it's a little-known fact that,]] often, the writers would leave spaces in the scripts ''blank'' for Cliff's LittleKnownFacts--as Ratzenberger was skilled at ad-libbing the appropriate pieces of trivia.
* WhatCouldHaveBeen: [[Series/MysteryScienceTheater3000 Joel Hodgson]] [[http://www.whmpodcast.com/2012/01/joel-hodgson-whm-interview.html revealed in a recent interview]] that he auditioned for the role of Woody Boyd.
** The network originally wanted to have Woody take over the bar after Ted Danson announced he was leaving after season 11. However, Woody Harrelson refused to do the show without Danson and so it was decided to simply end the series.
** [[{{Newhart}} Julia Duffy]] was the first choice for the role of Diane.
*** [[JustShootMe Wendie]] [[HotInCleveland Malick]] also auditioned for the part.
