Natalie's restaurant was famous for its nightly contests where ice fishers competed to see who had caught the biggest, strangest fish. It was so well-known that even during the summer people ate there to see where all the excitement happened, in the same way that people line up outside the Bull & Finch even though the actors from Cheers are never there.

Making your way evil today sure does take a lot.
Thinking of ways to distribute hate takes everything you got.
Wouldn't you like to rule a place?
Sometimes you wanna go where everybody hates your face
And the villains share your rage
You want to be in the evil seat, heroes are all the same.
Adventure Time: The episode "Simon & Marcy" has Simon sing the Cheers theme tune and briefly act out an episode to entertain the young Marceline. He even sings a Dark Reprise of the Cheers theme when losing himself to the Crown's influence, to keep himself from going completely bonkers.
Adventure Time: Fionna and Cake: At the beginning of "Fionna Campbell", Fionna is annoyed that the show seems to be playing on every channel. Later in "Simon Petrikov", the theme song plays over a montage of Simon waking up and starting his day. The final episode of the miniseries, "Cheers", is a reference to the show.
The Critic: In "Dial "M" For "Mother", a stoner couple misindenties Adolf Hitler as "The mailman on Cheers" (Cliff).
The Simpsons has a whole bunch of references, in part due to Kelsey Grammer being a recurring guest star as Sideshow Bob.
"Flaming Moe's": After Moe steals Homer's secret drink, his bar becomes a rousing success. An extended sequence parodies the Cheers intro, playing a riff on the theme song while showing assorted moments in old-fashioned engravings. Moe also hires a waitress based on Diana, who ultimately leaves to pursue a career in Hollywood (though Moe thought she was better off staying put). Barney becomes more like Norm and has some interplay with a Woody-esque bartender.
"Marge on the Lam": With Marge having a girl's night out, Homer goes looking for some companionship. Arriving at Moe's, he says, "Sometimes, you gotta go where everyone knows your name." He then sees Moe threatening a customer.
"Fear of Flying": After being banned from Moe's, Homer goes looking for a new hangout, and Cheers is one of the places he tries out. Sam is up to his old womanizing ways, with Carla questioning if he can pull it off ("Sam you're too old to be dating two twins on the same night you're supposed to marry Diane without Rebecca knowing"). Norm angrily tries to attack Woody for refusing to serve him another beer, with Cliff and Frasier barely able to restrain him. This craziness convinces Homer to flee. All of the cast members reprised their roles for these cameos, save (ironically enough) Kelsey Grammer. He was unavailable, due to a scheduling conflict.
"The Strong Arms of the Ma": Marge is traumatized by a mugging and refuses to leave the basement. While the family has dinner with her down there, Homer observes seeing all the people walking by on the sidewalk reminds him of Cheers.

One of them was Cheers, with Homer as Norm, Marge as Diane, Bart as Woody, Lisa as Carla, and Maggie as Cliff. They get chased off by the sudden arrival of Sideshow Bob (standing in for Frasier). This Couch Gag appeared in a few other episodes over the years.
"The Bob Next Door": Bart says the new neighbor sounds suspiciously like Sideshow Bob, but Homer and Marge assure him that lots of people sound like him and point to "Frasier on Cheers" as an example. (Incidentally, "Frasier on Frasier" was another example.)
"The Town": The family goes to Boston, so quite a few references abound as sight gags or musical cues. Norm, Carla, and Cliff are also briefly seen as background characters during a parade.
