Pranks!

[TheOnlyOneHeFears]

Yup, I finish school this week to go on study leave before GSCEs, and, naturally, it's prank time on Friday So, I want suggestions from you as to what pranks I pull. Stories about successful/hilarious pranks you've done would also be cool.
I've only got a few planned so far.

1. Crushed up laxatives in the water jugs in the canteen
2. Frogspawn/some other disgusting jelly-like substance in the bottom of the vending machines.

Suggestions please!

Step 1: Get a zillion ketchup packets.
Step 2: Fold ketchup packets in half.
Step 3: Place folded packets under the bumps on the toilet seat of every toilet in the school.
Step 4: Run like heck.

Another thing you could do if you live in the right place is go into a grassy of woody area, catch as many ticks as you can, and release them in every classroom exept yours. And now for a favorite of mine: Write mushy love cards to as many girls as you can, but sign as someone else.
About putting a gooey substance in vending machines: Use worms.

Lock all the bathroom stalls from the inside.

I've said it before and I'll say it again:

Boot every PC you can get your hands on off a DOS floppy that automatically loads an old game you have to reset to get out of, like Alley Cat or Dig Dug. (You could also mix it up and use Frogger but you need a slowdown utility to get it to run properly, which adds to the boot time, thus increasing your risk of getting caught and decreasing your effective range.)

Here's a couple of pranks people did at my school:

1. get 3 pigs. number them 1,2, and 4 but don't tell anybody there's not a number 3. set them loose in the school

2. Get a cow and put it on the top floor. Cows can't walk down steps

Lol the seniors at our school did both those exact pranks last year. The year before, a bunch of them streaked across the whole school. One time the school was sporked, where they took thousands of plastic forks and stuck them in the lawn every few inches.

Sporking is a cool trick until the janitor figures out that he can just suck up all the sporks with a big magnet. Also until the janitor makes you squeal like Pig #3.

Good luck using a magnet on plastic.

My friend put a program that makes a list of random 1's and 0's onto someones calculator and told them it was the source code. Keep in mind that he goes to a high school that focuses on engineering, so the kid thought my friend was really smart to be able to find the "source code".

Oh man this brings back good memories I did that when I was in 8th grade, but I only did it to the toilets in one bathroom. I did it during lunch, then a few classes later I went in to check the stalls, and there was ketchup splattered all over the toilet bowl. I was laughing so hard. Can't help but feel sorry for the poor soul that sat on them.

I have something to add:
When you put the ketchup packets under the knobs, make sure the folded end is NOT facing the inside of the bowl. That way the ketchup will shoot out of the sealed ends.
And you don't necessairly need to run. In my opinion, someone running out out the bathroom seems a little odd.

A classic: fill a cup partially with water (or something else) and put it on top of a door that's partially open. Works every time. We like to do it to the new guys at work.

My cousin is in college, and he and his friends would tend to buy cakes and brownies and whatnot. His roommate would very often scarf down whatever was left. So once, they cooked laxative into some brownies and left them out. Needless-to-say, the results were highly amusing.
