The classic sitcom "Seinfeld" mined a lot of its humor from the ludicrous things done by its four self-centered leads, but one of the funniest bits on the whole series focused on George Costanza (Jason Alexander) telling actor George Wendt, playing himself, that "Cheers" should take place somewhere other than a bar. It's impossible to imagine having the audacity to tell Wendt, who starred as Norm on "Cheers" (and a bunch of other shows) something that bonkers, but it's well within George's purview, and it goes about as well as you can expect, with Wendt eventually making fun of George on television, in front of a live studio audience. This all goes down in the season 4 two-part premiere, "The Trip" (the only episode that does not feature Elaine, played by Julia Louis-Dreyfus), leading to pure humiliation for George.
