History YMMV / CHEERS

* BaseBreakingCharacter: Diane. To her fans, she's the biggest sweetheart, TheCutie, and something of TheWoobie. To her haters...

* SeinfeldIsUnfunny: While the show is still beloved in television circles, one of its main calling cards in the first five season has fallen into this, with Sam and Diane being the TropeCodifier of BelligerentSexualTension and WillTheyOrWontThey of American sitcoms, long before ''Series/{{Friends}}'' took the baton in the 1990s. That a sitcom could write an ever-evolving arc between two love interests full of tension, putting them together, breaking them up, and then teasing a reconciliation captivated audiences beyond the show's strong ensemble and writing, a dynamic that's ever-present in many a sitcom today. In fact, the series was ''too'' effective with this; one of the factors in Shelly Long walking away from the show was over her frustration with the writers' reluctance to fully commit to Sam and Diane's endgame of whether they'd get together for good or not.

** After Lilith finds out Frasier was married once before her and Diane she starts crossly referring to him as her "first husband" which loses some of the humor considering she does divorce Frasier and marry someone else (who in turn leaves her).

** One episode has Frasier and Lilith discussing the fact he stalked her between their romance and their marriage, which is played for laughs, Frasier even triumphantly commenting "worked, didn't it?" Hell of a lot less funny in this day and age -- though that was a major plotline of ''Series/TheBigBangTheory'', ''Series/{{Friends}}'', and so on.

** In the finale, the SlapSlapKiss and BelligerentSexualTension dynamic is treated as the way it really is: toxic and a sign it's good that the two never ended up together. This dynamic would later become popularized in 90s and 2000s media, with these couples still forming relationships and ignoring the toxicity.

** Many fans like to believe that the customer in the show's final scene that Sam shoos away because the bar is closed is the same MinorWithFakeID that tried to get Sam to serve him in the first episode, now old enough to drink legally.

** All the Boston Red Sox jokes. The Boston Red Sox, after a long losing streak, would go on to win the World Series in 2004, 2007, 2013, and 2018.

* HeartwarmingInHindsight: One episode has Woody's parents request that he come home, believing that Boston is too dangerous for him. They change their minds after Al sends them a message saying "Let your son pick his own path and it will all come back to you." Near the end of the series, when Woody is elected to the city council, he's proven right. (Pity Al didn't live to see it.)

** In the finale, the SlapSlapKiss and BeligerentSexualTension dynamic is treated as the way it really is: toxic and a sign it's good that the two never ended up together. This dynamic would later become popularized in 90s and 2000s media, with these couples still forming relationships and ignoring the toxicity.

* ValuesResonance: Lillian's daughter is openly romantic, but doesn't want sex, which would be the definition of asexual relationships. Zigzags with ValuesDissonance since it's not treated as a natural sexual preference, but the result of childhood trauma (her father died as a result of too much sex with her mother).

** Radio/GlennBeck had one appearance, in "Severe Crane Damage".

** In the season 2 episode “Fortunes and Men’s Weights,” Coach describes a salesman who conned him into buying an antique scale as being like [[WesternAnimation/RickAndMorty a cross between Abraham Lincoln and Adolf Hitler]].

** Sam Malone: A deeply insecure and lonely man who carefully cultivated his facade of a womanizing dumb jock to fill the void in his life and feed off the adulation of the regulars of the bar. There are several instances where he lets the facade down and shows his hidden sensitivity and intelligence that he dare not let the other guys see.

** Many fans like to believe that the customer in the show's final scene that Sam shoos away because the bar is closed is the same MinorWithAFakeID that tried to get Sam to serve him in the first episode, now old enough to drink legally.

* {{Fanon}}: Quite a few LGBT Cheers fans like to headcanon Norm, especially in the later seasons, as a romantic asexual, mostly due to him not wanting to have sex but still loving his wife dearly. Even early on when there was a subplot about Vera wanting a child, Norm indicated that he didn't enjoy trying to get her pregnant and only did his part to make her happy.
