I accidentally called one of my teachers a fukcer to his face.
I did the Nazi salute in class when we had a German exchange student there to give a speech (I made sure he didn't see it but the teacher saw)
In one class period I blew up balloons (from paper machei from Spanish class) and popped them to startle the class, I criticized my teacher's wife calling her crazy, insane, luny, etc... and I was flat out loud and interrupting class when we were supposed to be quiet to work.
These were all to the same teacher even though he was one of my favorites.
