ok, this is gonna be a long post, I'll tell you up front
So far,
one teacher had a bit of a temper, and when one of the students had been uninterested and to him "provocative", he jumped up from his desk, got to the desk of the student, dragged him to his feet, almost carried him to the corner, took his head and made him headbutt the wall 3 times, yelling: "Just to make sure I won't see your ugly head again."
Immediately after that, my neighbor in class laughed out loud and pointed: "haha, good doggie on a leash."
The teacher started fuming, marched over to us, and grappled the scrawny kid next to me, who held on to his desk yelling "lemme go, lemme go". The whole dragging and headbutting process got repeated once more.
Keep in mind we were about 15 years old at that time.
so much for injury from a teacher.
Other than that, we once talked a substitute into forgetting to teach his class and play his bagpipes for 40 minutes during class.
Same teacher (chemistry): I started a fistfight last hour of the week because of some idiot behind me. (he let us off without a word)
Same teacher tried to get the class to quiet down, struck his counter with a 50cm ruler, broke it on impact and couldn't keep laughing himself.
Same teacher (there's a pattern here somewhere, probably because it was the last hour of the week

): We were taking down the solution off the blackboard when suddenly the guy next to me almost dives in his backpack, starts to blow and blow, and the next thing I know, there's a blow-up doll with double D's and any anatomically correct orifices, being tossed around the classroom. Made the teacher yell out: "Put it away, before I hit it." Which naturally led the class to chant: "He'd hit it, he'd hit it"
Also got a kid to sit in the corner, and piled about 16 chairs on top of him, so he couldn't move. This again happened during chemistry class
Another chemistry-teacher had some fun making a Tie-Fighter out of atom-models and flying it behind our heads murmuring "I am your father Luke."
We managed to get one guy in front of the counter at physics class (solid counter, so he was effectively invisible from the teacher). And each time the teacher would turn around to write on the blackboard, we'd give him a signal. He'd get up, take something off the counter and get back down. He managed to clear about 3/4 of the counter (which was an impressive amount of stuff) before he took the teacher's notes... When he turned around, he finally noticed there was something missing
Keep in mind, all these things were never met with any repercussions, the ones that did, I have omitted
yeah, I loved highschool
