Seinfeld Quote

Keith: Elaine, you don't know the first thing about first base.
Elaine: Ha, ha. Well, I know something about getting to first base. And I know you'll never be there.
Keith: The way I figure it I've already been there, and I plan on rounding second tonight at around eleven o'clock.
Elaine: Well, uh, I'd watch the third base coach if I were you 'cause I don't think he's waving you in.
