What can i pull at the end of school

well I want to pull a really great prank at the end of school but me and my friends dont know what 2 do

Watch a few videos on youtube about a old mtv show called high school pranks. Also get a bunch of bouncy balls and put them all over the school, but be careful you might get in trouble.

My school end year pranks usually are penis related... Here something they did last year.
So after making this weird liquid, I heard it was piss kept in a bottle for a few weeks, they poured it on the grass to make a you know what shape. the grass died where the liquid touched and it's been there for at least a year. Funny thing is that if you view Leland High school California on google earth you can see it XD

hmmm nice c 4 me I pulld 2 it took all da homies in da skew. but we got abuncha balloons got vineger and baken soda. and as much food colorin as we culd. we got 2 skew real early and filld da baloons and we snuck n2 every class we had so all 2gether like 300 classes and we hid dem in da teachers desk and students desk. after we did that I hackd n2 da skew comp because da last day of skew we alwaz a=have an assembly so when changed da video dey had and made our own video of us setn all da stuff up in da classes and we wore mask so no1 knew so da bell rang and we went 2 class and our teachers are alwaz rollin round in dey chairs so that set those off and kids movein in dey seats set those off and it was like a skew full of skittles and den da whole autatorium was filld wit all dese colors and dey played da vid and it was HYYYLAAARIIIOUS. I tink da best prank and our skew history hope I sparkd your brain and gud luck

use round-up to leave a message. it does an awesome job also.
I pee off the back of my back porch and all it does is make the grass greener!
Get a gallon spray bottle and set it for full stream and wright your message and it will take a few days to show up and will last and you are not there!

before you do a prank, you better know you need to cover your tracks and watch your asss. you can get expelled easily for a prank, and if you do it as a senior you'll have to repeat the year!

Take 3 goat, and number them 1, 2, and 4. release them into the school. once they catch the goats, they'll spend the rest of the day looking for 3!
