"The Aristocrats" is a taboo-defying, off-color joke that has been told by numerous stand-up comedians and dates back to the vaudeville era.[1] It relates the story of a family trying to get an agent to book their stage act, which is remarkably vulgar and offensive. The punch line reveals that they incongruously bill themselves as "The Aristocrats".[2] When told to audiences who know the punch line, the joke's humor depends on the described outrageousness of the family act.[3][4] Because the objective of the joke is its transgressive content, it is most often told privately,[5] such as by comedians to other comedians.[6]
