Don't Laugh: Classroom

Batsu Games ....Perhaps the best known Gaki no Tsukai episodes are those dealing with batsu games, or punishment games, in which one or more of the cast members are subjected to after losing bets, major competition, or physical challenges.

The "No Laughing" Batsu Game itself (broadcast annually during the New Year's Holiday) was first introduced in 2003. The premise of each "No Laughing"-punishment game is, the losing members of the cast have to endure many compromising, absurd, generally ridiculous situations for a long period of time (up to 24-hours, thus far) but must refrain from laughing at any of them. Whenever someone does laugh, and he is caught by A Watcher, the announcer of the game will declare that person as having just become "out" (アウト or a-u-to in Katakana); immediately afterwards, the appropriate number of "hang-men" will come out to mete the rule breaker's punishment. (To date, this has been executed via single strikes on the buttocks {or somewhere in that area} with a weapon — one which does not change mid-game.)

To keep the Gaki no Tsukai Guys on their toes, there have been occasions where other conditions besides laughing had been set that could make them out, if fulfilled; also, the "victors" of the prelim-trial (if there are any) can make appearances during games to wreak further mischief and potentially cause even more discomfort to the losers.
