This improv game is in the following improv game categories:
2-4 teams of 2 players play a competition. They play rounds of improvised scenes, the titles (or "themes") are provided by a "referee" . Themes may include limitations like "no speaking", or a style ("western"). Teams get 5 seconds to "prepare" before the scene starts. Preparation time is called "caucus". The audience votes which team wins the point.
The catch aspect refers to the extravant dressing up of the teams, like westlers in a catch match. Be it that the teams not neccesarily dress up like catch players; any type of dress-up goes.
