Clowns are comic performers, stereotypically characterized by their colored wigs, stylistic makeup, outlandish costumes, and unusually large footwear. Clowning, in its most basic form, can be described as drama without a fourth wall. In other words, a clown acknowledges his audience. The clown's humor today is often visual and includes many elements of physical comedy or slapstick humor.

Clowns spread in cultures of any time and place, because they meet some deeply rooted needs in humanity: violation of taboos, the mockery of sacred and profane authorities and symbols, reversal of language and action, and an ubiquitous obscenity. An interesting example can be found in the Native American clown societies.
