S1·E69 Poop is in Heaven, So The Student Council Come

Bossun wants to poop so bad. But he faces many troubles from the toilets he wants to use, like the school toilet's being broken (thanks to Dante), a convenience store's toilet being investigated by the police so Bossun can't use it (thanks to a robber), forgetting his home key, mistaking his home for a woman's and ending up presumed a pervert (his trousers undone when the door opened).
