Survive a day in school

You rush forward. "AIYAIYAIYAIYAI!!!!!" You run forward and backslap the teacher, then kick her to the ground. You then take your seat. She calls the principal but everyone denies your actions (this teacher is hated.) She is fired for lying and you are given countless apologies. Eventually a new teacher comes in- this one is a military teacher. How to get rid of him? Everyone hates him as well.
