Press the green flag! How teachers see sharing food. No wonder they don't let us. o_0 The cutscene is when it switches to the teacher's point of view. If you don't get it, after the teacher stares at the student, it's what the teacher sees.
All credits to DerpAnimation, who somehow does fantastic animations without fancy animation programs! Basically the same movie, but I recorded all of the songs except the outro myself... lol.
