"Never Smile at a Crocodile" was sung by Mary Louise riding a crocodile through the swamp in episode 114 of The Muppet Show. Along the way various frogs get eaten by the crocodile.

The tune of the song comes from Disney's version of Peter Pan, with lyrics which were added later on subsequent record releases.

According to a 1978 Muppet Show Fan Club newsletter, this musical number was the longest shoot of any scene on The Muppet Show at that point.
