A double act, also known as a comedy duo, is a comic device in which humor is derived from the uneven relationship between two partners, usually of the same gender, age, ethnic origin, and profession, but drastically different personalities. Often one of them, the straight man, feed or stooge is portrayed as reasonable and serious, and the other one, the funny man or comic is portrayed as funny, unintelligent or unorthodox. When a woman is in the "straight man" role, she is more often referred to as a comic foil. The term feed comes from the way a straight man will set up jokes for - or "feed" them to - their partner.
