Downtown.

Downtown's 'No Laughing' Game is based on the Japanese comedy show called "Downtown Gaki no Tsukai". Basically three people will be going to chibicon doing what everyone else will be doing, the only difference is that whenever any of the three laugh, they get punished! The punishment will come in the form of Ninja bending them over and hitting them on the backside with an object.

The objects will be;

A Shinai.
A Bokken.
A Riding Crop.
