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

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).
