Physical comedy is a form of comedy focused on manipulation of the body for a humorous affect. It can include slapstick, clowning, mime, physical stunts, or making funny faces.
Physical comedy originated as part of the Commedia dell'arte. It is now sometimes incorporated into sitcoms; for example, in the sitcom Three's Company, actor John Ritter frequently performed pratfalls (landing on the buttocks). Cartoons also commonly depict physical comedy, such as in Tom and Jerry and Wile E. Coyote and The Road Runner

Slapstick elements include the trip, the slip, the double take, the collide, the fall (faint) and the roar.
