Never laugh at the 23rd issue of the library. In some cases, when the recording starts, the participating members must not laugh. Once you laugh, you have to accept the corresponding punishment. The idea of "laughing and being punished" was put forward by Hitoshi Matsumoto. It is Hiroshi Fujiwara, a former downtown agent, who promotes the normal operation of rice balls. In this project, Hiroshi Fujiwara played a joke on one of the five members with rude words.
