feeling kinda nostalgic today, and looking to see others nostalgy (or current time)

Post those nasty things you have done to a teacher!
Also post the worst thing a teacher has done; what was the worst/weirdest story of your school!!

(this part was lost in RAINBOWS)
Another one was to put a tack into the english teachers chair and that thing was stuck in my teacher's "lower back".

My 4th grade teacher beat up a student, that was kinda hilarious hilarious!
She beat him because she had gave him warnings all day, then he called her some curses and stuffs and she beat him. seems awfull, but that moment marked all of our class childhood.

There was also a woman of the cleaning crew that was caught having a "bad thing" with a teacher

Our friend (who was expelled) grabbed a hammer and stuck it (by the sharp end, used to get nails out) on another student's head, then start laughing! The other student just suffered a brain concussion. and you should never try this at home, or anywhere

There was also one who slept during classes! Nice school hum?

So what's the worst things that you have done to a teacher??

"this thread is not to offend anyone, and i'm sorry if it does"
"i didn't approve this act; well i kinda approved it once when i was younger so..."

Watch yourself so you dont meet the Loli Ban Hammer

Last year, I "accidentally" threw a water bottle at my Geometry teacher.
The next day, she showed one of my FrUk doodles from my notebook on a projector. It was kinda explicit, and everyone was staring at me. XDDDD
Then she gave me a detention. That's the reason she was my least favorite teacher.
