I didn't like my Earth Science teacher in high school. Once when he was alone in the lab I slid a board through the door handles so he couldn't open them from inside. He had to get out through a window. I also took a cow eyeball from the biology lab and put it in his coffee when he went to the office.

how creative u are, walter_mellon!haha. it seems that you really a good student, Aisuly. Actually i didnt    

play any joke to my teachers. I love them and we are good friends forever. :)

Whe i was sixth class ,we had a teacher on Russian language she always brought with apples and sweets afterward when left the class then were stealing on some  sweet out of her bag then she noticed and started leave her bag at  the guard.Or once had broken the desk and propped it to the well

I have been out of school for over 42 years.  I would still not reveal the pranks I got up to at school.
