Anyone know the name of the episode where bart goes to work for the maffia; he fails to turn up to a mob meeting, blaming principal skinner for his absence. The mob in turn "meet and greet this individual" and everyone believes they killed skinner; it turns out he was trapped under some storage stuff and occupied himself by seeing how many times he could bounce a ball whilst trapped, and then trying to beat that target - i think he was there for a few days. classic episode, anyone know the name??
