The show started with a conversation about the show, which was entering its fifth year. They then watched the an investigation of "Aunt Mimura" from Ep. 200, where the staff recorded her one-day activities. Murakami then realized that Aunt Mimura also came to the studio. after doing the Aunt Mimura Dance, they watched an investigation of notebooks. They found a man who wrote others' name like a 'Death Note', a woman with her feng shui notes, and a man who can't understand his own writings. After that they did an investigation of unseen things like Ep. 195. They asked the origin of badminton shuttle feathers, check whether cigarette smoke can come out from a hole of pierced nose or not, the spanner for giant nut, and rejected material of impersonator comedians. Murakami then read a fact about how sleeping less than 6 hours might increase risk of early death. Matsuko commented that the staff putting the fact is like asking people to take care while asking them to work hard at the same time. (Source: kisskh)
