In the episode where Sam thinks he has impregnated a girl and vows to give up sex for a while if God gets him out of this one, Frazier suggests that he should channel all of his pent up sexual frustrations into playing the piano. Now, pay close attention to the very last scene. When Rebecca walks out of her office and asks Sam to zipper up her dress, he starts to zipper it DOWN and Frazier walks over, grabs Sam and says: "Sam, Sam! Piano, Ted. Piano. For God's sake, piano!" He just called him by his real name: TED Danson!
