well, i got expelled form my second primary school school just because loads of little things
but the school i am in now i very very nearly got expelled because...
me and a friend nicked a washing up liquid from the kitchen next to the vice principles office *sly or what*

. put it in to ordinary non see thro drinking bottles and spent the rest of lunchtime squirting it every where

(you should try it cover the hole toilet block in washing up liquid go in to the middle of the room move ya feet around a bit and try to not to fall over) haha) anyway squirting it everywhere on stairs, door handles any potential slippery surfaces. oh that was fun.
they said that we weren't expelled cus no one was had hurt then selves, but i know for a fact hat one of my friends had fallen over and got a bit hurt. hehe glade they didn't say anything
