Synopsis

Television parodies featuring the Osomatsu cast. The older set does some calisthenics with disastrous results, Jyushipi and Choropi conjure up some magical cooking, the sextuplets and their parents involve themselves in a yakuza movie-style argument, a sextet of singing fungi try to escape their fate of harvesting, and the Idiot Brothers, Idiot Sisters, and Idiot Married Couple partake in a manzai sketch comedy bit.
