Comedian/actor/funniest man on the planet Louis C.K. was on Letterman on Tuesday to plug the latest Woody Allen film, Blue Jasmine. Louis C.K. has a small role in the film as he plays the boyfriend of one of the major characters. Perhaps uncoincidentally, fellow comedian Andrew Dice Clay is also in Blue Jasmine and plays a former flame of C.K.'s love interest.

During his segment on Letterman, Louis C.K. says that he and Dice have become friends and that, once you're friends with Dice, you just can't shake him. He sets out to prove this by playing a voicemail from his daughter followed by a creepy voicemail from his new buddy.

What's most surprising about the message is, probably, that Dice doesn't start it out with, "Hickory, dickory, dock."
