Sam pretends to be a famous heart doctor
Diane: He's having chest pains, Doctor.
Sam: Why don't you time them and see how far apart they are?
Frasier: (when a schoolmate forgets who he is) You open a few thoraxes together and you forget who your friends are.
Frasier: You didn't want to eat [at The Cafe] anyway, Sam. The waiters pride themselves on rudeness. The portions are too small and it's exorbitantly overpriced.
Sam: You couldn't get in either.
Frasier: Not till April.
Diane: I have the most exciting news everyone. Tonight I am eating dinner at The Cafe.
Sam: Gee, that's pretty exciting. Tonight I'm driving home in the car.
Cliff: Today marks the beginning of my seventh year as a United States postal carrier.
Norm: Woody, I think that calls for a little drink on the house. What do you think?
Woody: I think you're right, Mr. Peterson.
Norm: What the hell give Cliffie one too.
