50 Ways to Leave Your Lover

Sung by Floyd and Janice in Episode 511: Paul Simon. They were backed by Animal on drums and Rizzo the Rat on cymbals.

Variations of this songs title seemed to be a running gag in that episode. During the cold opening, Paul Simon says that he knows "Fifty Ways to Love Your Lever", Rowlf asked Floyd and Janice during the song if it's actually "Fifty Ways To Love Your Lever", and in that episode's Veterinarians Hospital sketch, Dr. Bob said that he'd operate by mentioning a Paul Simon song... "Fifty Ways To Lose Your Liver".
