I recall an old Woody Allen movie where he plays a Court Jester who's got the hots for the local Queen. The King doesn't like unwanted suitors, so the Queen wears a "chastity belt" (Yeah, that's a good one for Wikipedia, if you don't know about them). The Court Jester tries to get the chastity belt off of the hot Queen, and gets his hand stuck just as the King shows up for some nookie. "I hate getting caught with my hand in the cookie jar."
Yeah, it's funny.
