Super glue in the chair (Note: Make sure after they sit down to talk to them so they do not get up right away takes a minute or so to work)

Water Fountain - this one worked for me sometimes. Stick a peice of paper/gum in between the last peices of metal where the water comes out of. Make sure its small!(If done right when someone goes to drink itll shoot all over their clothes).

Back Signs - This is very dumb but yet amusing. Grab a peice of paper and write something funny on it and then get some tape and put it on the paper make sure the tape is somewhat long. Then walk behind them and kind of make the tape stick on them so they dont feel you touching them then let go. (note: do not do Kick Me that is very old, Do something like I like it hard or whatever).

Wireless Mouse - If you own a bluetooth wireless mouse bring it to school one day and plus in into your teachers computer or friends. start click on programs and clicking out of things or even yet restart the computer.

Cell Phone - ask to borrow someones cell phone and tell them you need to text someone cause you do not have a phone. Call your phone on their cell phone so you get there phone number and turn up their volume to high. Then when its all quite in class call them.

Sleeping Kid - This only works sometimes depends. If you see a kid sleeping wake him up and do not smile and say " the principle wants to see you ". Sometimes theyll freak out and walk out of class and the teacher will yell at them or they wont believe you.

Laxative - go buy some laxative from the food store (medicine isle, or rite aid, walgreens) now when your at lunch with your friends when they are not looking take there main dish and put laxative in there.. if its the liquid laxative use their drink.. they will hate you forever when they are in class and they run out the class and stay in their the whole class period(note: Do not say it was you)

Love letters - This is always fun write a letter in class and label it from someone in class to someone else such as: From Ryan: To Steve. Yes it could be both guys its whatever. Then write something really cute and romantic like this: Hey steve i love your hair its no cute, i wish i could see you every day your amazing. i want to lick your feet. This really freaks out people and it is funny as hell.

Tampons - Go buy some tampons and then pour ketchup on them and distribute them around campus.

Cheerleaders - This one was funny spread itching powder on the cheerleaders pom poms

Vending Machine - Pour something slimy such as pudding. then pour it into the change return slot. when people get their change out theyll put there hand in the pudding and freak.
