Jerry: Boy, do you smell something?
Elaine: Do I smell something? What am I, hard of smelling? Of course I smell something.
Jerry: What is it?
Elaine: I think it's B.O.
Jerry: What?
Elaine: It's B.O. The valet must've had B.O.
Jerry: It can't be. Nobody has B.O. like this.
Elaine: Jerry, it's B.O.
Jerry: But the whole car smells.
Elaine: So?
Jerry: So, when somebody has B.O., the O usually stays with the B. Once the B leaves, the O goes with it.
