Slippery Floor
Before the bell rings, spray WD40 or any lubricant all over the hallway floor. When students come out of their classes, they will slip and slide and some will fall and get their clothes all messy.

Bubble Gum Hair Prank
Place some chewed gum in the hood of someone's jacket. When they put there hood on their head the gum will stick to there hair. I know, its cruel. But just so you know, peanut butter will help the gum come right out.

Bug In A Pen Cap
Classmates are always asking to borrow a pen. Next time you find a dead bug, place it in a pen cap and close it. When the next person asks to borrow your pen, give them that one. They will be in for an insect surprise!

Fake Dog Poo
Put some fake dog poo under a classmates desk. Brown Play-Doe works really well and looks real.

Paper On The Seat Prank
Place a piece of paper on your victim's seat. Try and find paper the same color as the seat so he or she will not notice. Then add a small amount of glue to the top of the paper. Your victim will sit on it and walk around with paper on his rear all day.

Tomorrow Is Substitute Teacher Day
If you can get into the teacher's lounge. 9 times out of 10 there is a coffee pot there. Most of the time unattended. Slip a couple of laxative tabs in there. The next day you will have a sub teaching the class!

Worms In Locker
Most lockers have vents large enough to slip some worms inside. Do this when your victim is away from his locker.

Military Recruiter Prank
Use your victim's name and address and mail the local military recruiter telling him how interested you are in joining the army. Schedule a visit while your victim is at home. Recruiters are very persuasive and are difficult to get off your back!
