It's a parody of the yearly no laughing game of Gaki no Tsukai. On every special during the past few years, pro-wrestler Masahiro Chono(played by the Hakurei Miko here) does a running gag every year where one of the comedians of the group gets put into a situation where he offends Chono leading to him giving said comedian with a slap. Said situation is often long and drawn out, leaving the other comedians to break into laughter, for which they get hit in the ass for laughing.
Ohh, it's the prison special!! XD I love yamazaki's reaction during that one.
