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 have 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.
