A special extended length episode where Downtown host a gameshow with the rest of the cast as contestants. They bring onto the main stage different guests or animals in pairs. Then they're asked a question such as which animal is female/male, the contestants must pick a side to go on. If they pick the wrong choice too many times they get a batsu. (NSFW Note: Topless women).
Some of the batsus in this are really "unique". Higashino's and Yamazaki's especially!
