George: ... Anyway, I'm thinking of making a big move.
George: I might tell her that I love her. I came this close last night, then I just chickened out.
Jerry: Well, that's a big move, Georgie boy. Are you confident in the 'I love you' return?
Jerry: Cause if you don't get that return, that's a pretty big matzoh ball hanging out there.
George: Aw, I've just got to say it once, everybody else gets to say it, why can't I say it?
Elaine: What, you never said it?
George: Once, to a dog. He licked himself and left the room.
Jerry: Well, so it wasn't a total loss.
