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.

The scene that came to my mind is of Walter Matthau in “Grumpy Old Men” with all the air fresheners in his car trying to mask the smell of the dead fish that Jack Lemmon put in there.
