After participating to a previous show where they have to bet or be challenged to any kind of competitions, the losing members of the Gaki no Tsukai are selected to spend 24 hours in a setting which they have no knowledge of the theme nor the course of the events. They are exposed to various absurd and crazy situations nonstop for 24 hours and must refrain from laughing. If they do so, hang-men appear and hit the rule breakers with a weapon (the weapon varies every year).

Produced by Hitoshi Matsumoto, Documental pits ten comedians against each other. The objective is to make each other laugh in a closed room. Each contestant brings a one million yen participation fee. The last person to stay in the room without laughing wins. The winner is awarded a 10 million yen prize and bragging rights as the funniest comedian.
