A joke (as told by David Lee Roth):

A man walks into bar and looks at the jukebox--all the records in it are by Tom Petty and the Hearbreakers. "Hey," he says, "Do you have any other records besides Tom Petty in this jukebox?" "No," said the bartender. "It's a jewkebox."

--So wait, Tom Petty is Jewish? What the heck! Is nothing what it seems?!
