History Series / Cheers

* ValuesDissonance: Probably the record for shortest time interval between the example and the values shift: Rebecca's dilemma with her spring-chicken boss's unwelcome advances was only ''three years'' before the Clarence Thomas confirmation hearings made sexual harassment a major workplace concern all over the country.

** Well, the idea's pretty much emphasized all throughout their interactions with one another (verbal or physical).

* YourMom: Of all people, it's none other than ''Diane Chambers'' who drops this! When the gang faces off against Gary's Old Town Tavern in a bowling match, Gary makes the mistake of daring to insult Diane's sorority. Diane's response is to stun the haters silent by filling in for Woody, and throwing a strike...following which, she gives Gary a devilish Look, and lets loose a throaty-voiced, "Yo MAMMA!"

* GoodPeopleHaveGoodSex: [[LampshadeHanging Lampshaded]] with this memorable exchange between Sam and Diane early in the Fourth Season, where they actually ''discuss'' when they first "made love":

* GoodPeopleHaveGoodSex: This memorable exchange between Sam and Diane early in the Fourth Season, where they actually discuss when they first "made love":

--> '''Sam:''' Yeah, you were pretty wonderful yourself."

** Also, the way various characters in ''Frasier'' desribe Hester Crane, the mother of Frasier and Niles, makes her sound quite different and much more sympathetic than the character seen in an episode of ''Cheers''. Since Hester died somewhere between her one ''Cheers'' appearance and the beginning of ''Frasier'', it's of course possible that everyone simply wanted to remember only the good things about her, but this discrepancy is never addressed.

** Other Series Continuity Errors with ''Frasier'', mainly Frasier referring to his father as 1) an eminent psychiatrist and 2) dead, were [[{{Retcon}} explained away]] on ''Frasier'' as Frasier basically lying because he was not on good terms with his father at that time.

* InformedFlaw: Diane and Rebecca both make jokes about Sam being dumb, but Sam is rarely portrayed as being stupid. He's definitely crass in his attitudes towards women, and a man of simple tastes (babes, baseball, TheThreeStooges), but not usually dumb. Contrast him with Coach and Woody, who actually do say dumb things all the time.

* NegativeContinuity: The show mostly averts this trope, but sometimes uses it when it comes to Cliff's romantic life. Humor is often drawn from Cliff being a very inexperienced bachelor, and sometimes it's even implied he's a virgin. However, in two different episodes he starts dating a woman, only for her to be completely forgotten by the next episode, so that Cliff can become the butt of jokes again. His third girlfriend, Maggie, has a steady relationship with him and appears in several episodes, yet between her appearances Cliff is still treated as a sad loner. For example, in a season 10 episode Paul is amused by the idea that Cliff would ever get married, even though he almost married Maggie earlier during the same season.

* NotEvenBotheringWithTheAccent: This is a show about a bar in Boston, Massachusetts, but of the regular characters Cliff is the only one with even an approximation of a New England accent.

* TheDogBitesBack: Frasier in "The Heart Is a Lonely Snipe-Hunter". It was his EstablishingCharacterMoment, and he didn't do it because he was mean or angry - he accepted being a victim of a snipe hunt because that's what guys ''do'' - and screwing the others would also be what guys ''do''. At that moment, Frasier earned some HiddenDepth.

--->'''Diane''': You, Sam Malone. are the most arrogant, self-centered, [[CurseCutShort son of a b...]]

-->'''Diane''': And he's a bookie?

** Diane borrows $500 from Sam to buy a first-edition Hemingway. Sam says he's not going to expect her to pay it back, but then Carla eggs him on by pointing out Diane's expensive clothes, lunches, etc. Finally Diane gives Sam the book as collateral; [[BrokenTreasure he drops it in the bathtub while reading it]]. A buyer offers Diane $1200 for the book, and Sam is forced to outbid him.

* TheGloriousWarOfSisterlyRivalry: Rebecca and her sister Susan(played by Marcia Cross) which Sam takes full advantage of to get into bed with both.

* PreviouslyOn: A couple of parodies and variations were used for the show, including an amusing recap narrated in a rambling fashion by Coach, who forgot significant plot details and had to start over.
