A parody of the song "That's Amore" by Allen Sherman has lyrics like
"When you're diving at night And your feet feel a bite That's a moray!" and
"When you see a big eel with its jaws made of steel that's a moray".
John F. Kennedy was apparently caught singing this song:

It's interesting to think what music and comedy would be like today without Allan Sherman. He was one hell of an innovator.
Edit - "How's your nephew Seymour? Seymour joined the peace corps. He's nice too." I love this stuff...:)
