Great ideas for pranks and stunts
 

Does anyone have any?

Here's mine.
Location: populated parking lot or strip mall
Supplies involved: a man thong and two cars
One car is the runner and the other is the spotter. The runner is the car I chase after. The spotter is the car looking out for cops, following me, and videotaping the incident.

First, after stripping down to nothing but the man thong and a shirt, The driver of the runner pretends to get in a fight with me, kicks me out of the vehicle, and locks the door. I chase after the car yelling out stupid shit like "At least let me finish changing!" and try opening the car door. After I get tired, I get into the spotter car and get away.

take a dump in somebody's toilet and then put in some instant gelatine or pudding.

put clear plastic wrap over somebody's toilet bowl. - this one's really good to do right after somebody goes to bed so they'll splatter the hell out of their bathroom when they get up to take a midnight piss.

put a very very very thin layer of powdered milk between somebody's sheets. their body heat and sweat during the night will combine with the milk causing them to smell like rotten dairy for a while.

Switch license plates of cars in a car park. Best done as a student on the right sort of day(Muck Up, leavers or April Fools) to avoid charges as it's probably criminal anywhere. It is however awesome.

Yell "WATER" in a crowded theatre.

Point to someone's chest and say "Hey, what's that you got there?" When they look down, quickly snap your finger upwards so you hit them in the nose. Then follow them home and kill them in their sleep. Make sure to get their family for added fun.

Yeah, so, can we get less actual malicious and/or criminal stuff before I have to descend upon this thread?

My last one's ironic modern performance art not a felony.;)

But as per your request, leave cakes or something non-threatening(so not packages) on the roofs of cars or various public areas and see how people react. 1000 points if you generate a news report containing the phrase "terror pastry".

Get a guy in a gorilla suit/anything surreal to pretend to fall asleep somewhere, and test the "Not my problem" field.

Here's my idea... you take a deck of cards, and pretend to be a street magician. Practice the trick of forcing someone to pick a certain card. When you're ready, go out and tell someone that you will tell their fortune. Have them pick a card that you made before, with nothing on it but the words "Your girlfriend is cheating on you."

You have to make sure they think it's just a deck of cards, of course. Then the actual message takes them COMPLETELY by surprise.

Bonus points if the person's girlfriend is there with them.

I'm sorry I ever doubted you.

I mean, I'm the first one who'd agree with the sentiment we need more bizarre shit in our everyday lives.

Once for April Fools day I took a large sheet of paper, wrote "gullible" on it, then glued it to a ceiling. When someone came past I pointed and said "look, the word 'gullible' it on the ceiling".

Some things I've always wanted to try are;

• Throw a box with just a flashing LED on it at some people (probably a bad idea)
• Something along the lines of the guy who managed to convince Jack Thompson that the Sims 2 had genitals in it

Back in the ancient times when I was in school...
 

...we dreamed of the awesome task of mounting all of a certain classroom's furniture to the ceiling, and inverting all posters, blackboards, etc. It would have been a fun prank...

Last I heard a group of people who I DID NOT KNOW NOR ASSOCIATE WITH managed to successfully sneak into 2 classrooms and exchange out all the furniture. It was mildly amusing.

The ideas of terror pastry or throwing a box with a flashing LED at people remind me of these. That, BTW, is something I long to do at my school before I graduate.

This is really elaborate. What you do is the day before april fools you pick a target and stage it so that he "accidentally" ruins something of yours. Tell the target that it was really valuble or something and make him feel guilty. Then you tell him that sometime within the next 1 or two days that you will take your revenge, but you will not tell him when. As he sweats it out, you need to secretly follow him to his dorm or something, and get his roommate to give you a key to his dorm. When he is out, you move some crap around and stuff, but thats all. After he sees that his stuff was moved around and leaves the dorm, you go back in and set the alarm clocks to some different time, preferably while hes asleep. and the rest is up to you, i would "borrow" all his pants or something, but the end is dependent upon your individual tastes, so you have to think that part up yourself, otherwise it wont work.

My math teacher always says "You two should go to bike racks to fight, " or "I'll meet you at the bike racks." Deciding upon a christmas gift, me and a friend went and unbolted the bike racks from the ground then carried them into his class before exclaiming "Merry Christmas!"

When we go on Band trips, we have to share a queen sized bed with someone else just to make the travelling economically feasible. So, my best friend Eric was absolutely piss drunk the night before. I made sure he was really asleep, and then put a chair on his bum and left it there. Waited a bit, then took it off. Then, I took off my shirt and got back into the bed. He wakes up, and I say "Good morning tiger."

I wish I had a picture of that look of abject terror on his face, especially after he realized his ass hurt.
