Greatest prank you pulled on another~

[Triumph]

My best friend used to bum smokes off me. So i took 3 or 4 matches and broke the heads off. I then took half the tobacco out of a smoke, put the match heads in and then put the tobacco in. Next time he bummed a smoke off me he got a hell of shock, when half way through the cigarette ignited.

That is ingenious. I swear I'm gonna use that one day...

Once I've put this note on a random car: "Hello, I'm sorry I scatched your car, for refunds please call this number." And I gave the number of my math teacher.

And another one took a little prep. We took a baloon, filled it with flour, then used up about 2 packs of gum, glued all the pieces to the baloon, and used some dark green playdough. Then we froze it and in the end we got something that looked like a fragmentation grenade. Then my friend (not me, I would NEVER do that) threw it through the window in the principals office... You can guess what happened next.

Fire in the hole...

I will do a print screen on someones computer at work, then hide the taskbar and turn displey icons off. Even if you reboot your settings are still the same(you can move your mouse but nothing happens when you click on icons/taskbar) so some people go crazy over this ^.^

When I was in the Air Force:
We would run into someones room and flip their TV or computer monitor upside down and turn the volume on everything way high then turn the power off.

I would create a task on someones computer in their room to play some random horrible song at 2:30 in the morning

I would ipsend people messages at work saying "I know what you did last summer" or "Get back to work, they are coming" etc etc

Umm I've done a ton more just can't think of them, heres a pic I found ~

Well, where I used to live, we would always go to the Rocky Horror Picture Show. They tend to have theme nights, like luau, catholic schoolgirl night, crossdressing, etc. Well, the theme of the night was crossdressing. My friend didn't want to crossdress so our friend kept joking him calling him a wuss and a chicken. It really pissed him off.
So we decided not to go that night. Instead.. while everyone was in the movie, we went and bought lubricated condoms and stuck them on the dudes windshield wipers. It was fortunately a rainy night.

This is a bit mean, but oh well...
When I was 11, I had a sleep over, and invited all of my friends. Well I had one friend who wasn't really a friend, she was an arse to me, and she treated me like shit. SO, while she was sleeping, I squirted honey in her hair.
That stuff can be hard to get out. Oh well, revenge is a bitch.
