"Never Smile at a Crocodile" is a novelty song written for the film Peter Pan, though it famously appears in instrumental form in the final film as Tick-Tock the Crocodile's leitmotif. It is the most famous song ever deleted in Disney history, though an instrumental version is played whenever Tick-Tock appears. The version with lyrics appears on Disney Sing Along Songs: Under the Sea, sung by Mark Miller and Richard Pursell. This song was also performed in Episode 114 of The Muppet Show, where it was sung by Mary Louise, Muppet frogs, and a Muppet crocodile. It was also heard in the TV special The Smithsonian Salutes Disney Music.
