The school announces a new event, Behavior Card Day. Behavior cards come in a wide variety of colors and rewards/consequences (reward, neutral and disciplinary card colors). Students can get rewarded, get the day off, or even get expelled. But this experiment will soon backfire as it faces controversy. Meanwhile, Joel and Otto accidentally set off the school fire alarms with a grappling hook and Murry gets blamed for it. Joel doesn't want to get punished so he tries to stay off the hook. Otto needs to help prove Murry's innocence.
