The Aristocrats (also known as The Debonaires in England) is a joke which has been told by numerous stand-up comedians since Vaudeville, and often only among an audience of other comedians. It has been referred to as "The world's funniest joke" and "the world's worst joke." It may be either depending on who's telling it, who's listening and the innumerable variations upon the theme. It has probably never been told the same way twice.

The joke always begins with a family walking into the office of a talent agency, and ends with the punchline "the Aristocrats!" The aim apparently is for the joke teller to fill in the middle by putting various members of the family into the most offensive sex acts and images the mind can conjure. Each joke-teller brands the joke with his own filth. The more tasteless, the better.
