ComedySports was started by Dick Chudnow in 1984 in Milwaukee. It`s a format of competitive improv comedy that resembles Keith Johnstone `s Theatresports . The format is currently played by a dozen-plus teams all over the USA, united in the Comedy League of America.

In a ComedySportz show 2 teams complete for points given by the audience. A referee oversees the match, times the games, calls fouls and gets audience suggestions. A match consists of something like 7 to 12 games, drawn from a repertoire of over a hundred improv games (you`ll find most of these games in the Games section of Improv Encyclopedia).

In terms of gimmicks, you have the `brown bag foul`, which is a brown paper bag placed over the offending player`s head.
