The Simpsons1989

[Homer is teaching a university course on marriage]

Homer:
I do have a story about two other young marrieds. Now, the wife of this couple had an interesting quirk in the bedroom. It seems she goes wild with desire if her husband nibbles on her elbow.

Mrs. Krabappel:
We need names.

Homer:
Well, er, let's just call them, uh, "Mr. X" and "Mrs. Y." So anyway, Mr. X would say, "Marge, if this doesn't get your motor running, my name isn't Homer J. Simpson."
