Aired on 2000, September the 24th. This the 3rd bus tour series. The Gaki regulars and a couple of special guests dress as anime characters (mostly female ones) and hop on to the bus. They then start to play a sort of game, the loser then have to get out and do something the winners decided on. Wait till the end for a little extra special clip.
