I beat the living crap out of a teacher since he always would give me bad grades for no reason. I compared my test answers with other people while they got it right and he gave it to me wrong. I tried showing him and he always says, "your special, that's why you get those grades." So one day I was pissed off and the same stuff happened to me, he told me that. i got up and beat the hell out of him. He went to the hospital for 2 days and I got suspended for 5 days. I didn't get expelled since he was doing this to me. He also got kicked out.

I kneed a teacher to the stomach for overly harassing my sister, if words don't work, your knees will do.
That teacher tried to get me expelled but the director/head master 'admired' my love for my sister telling me I have either loads of guts or I'm just too stupid. :l

When I was young I jumped out of the classroom, because I needed to stay 2 hours longer. Got suspended!

A lot to tell
I think that the most stupid thing I've done, was to drive away with my principals car

But that son of a bitch deserved it. He kept telling to all students "You are all worthless, you piece of shit! You will never get a job! Go kill yourselves".
So I and a couple of my mates stole his car keys from the teacher room, drove it to his house, and demolished it with stone, baseballs

He's still trying to find out who did it xD

...and I thought obtaining all of the staff's passwords was bad.

My school is pretty strict.

I don't know what is the stupidest thing I have ever done. But, somehow, my teachers know I smoke weed.
