Seinfeld & Chickens

FRANK: Let me understand, you got the hen, the chicken and the rooster. The rooster goes with the chicken. So, who’s having sex with the hen?
GEORGE: Why don’t we talk about it another time.
FRANK: But you see my point here? You only hear of a hen, a rooster and a chicken. Something’s missing!
MRS. ROSS: Something’s missing all right.
MR. ROSS: They’re all chickens. The rooster has sex with all of them.
FRANK: That’s perverse.
