i watched an old video of domoto kyoudai episode where tsuyoshi told a story when they are at hawaii. im not sure if this is right but i think tsuyoshi talks about he is drowning when they are at beach while koichi is playing volleyball or something.. at that time the whole guest n audience laughing on tsuyoshi's narration but koichi just smile sadly on the other side. ugh my japanese still no good i cant understand the whole story =.= i wish there r someone can translate the eps sobsobsob
