Peashooting Extreme
Once upon a time in first year of high school, we used to terrorize the teachers with hollow pen tubes + little bits of chewed up paper. Everytime the teacher turned his/her back, we'd pull out our arsenal and go into a frenzy of barraging said teacher with little wet soggy bits of paper. It was hilarious, but me, being the one who always went/still goes that one step too far, decided to chew up a full sheet of A4 paper for around half an hour. After half an hour i had what can only be described as a warm soggy snowball, I waited for the teacher to turn her back, and launched it as hard as i could (aiming for either the back of her head or the whiteboard - although head would have been funnier). Mid flight, the teacher turned back round facing towards the class, and gets a face full of runny paper and spit, splattering all over the place. Only this time she knew who the culprit was because I fell off my chair howling with laughter.

Result? Suspended for 3 weeks.

Bonus.

At my school in Cape Town
They substituted the paper for the plastic bit at the end of a shoelace with a pin jammed through it to make a rudimentary dart.

Being hit in the leg with one of those hurt like a bastard I can tell you...

I can imagine.. When I'm drunk I'm known to do Jackass style stunts in front of my mates. Once let a mate of mine throw darts at my hand against the wall.. Having a dart stuck half an inch into the palm of your hand also hurts like a bastard!

(I'd do it again though I got £20 last time as it was a bet!)
