3 Teams. 23 Minutes. 4 Rounds.
Because nothing says "hilarious comedy" like a series of numbers.

Catch 23 is an improvised Comedy Deathmatch. Three teams of improvisers battle it out in four rounds. They each have 23 minutes to use over the course of the night - no more; no less - with nothing but a 1 minute warning to guide them. Each scene is judged on a ten point scale with five points given by the audience and five by a hell judge.[more]
