Exactly!!!

This is what I did to my Assistant Squad Leader(a real bastard) last year.

We found out what his car was, and we left a note on it saying "The people who are watching me write this think I'm putting down my insurance information".

He went nuts looking for a ding/dent.

Also when I was in the Navy, A friend of mine went to a motel with his girlfriend, and a bunch of us picked up his car (an old VW rabbit) and moved it onto some grass.

Grandfather of a guy I know tried to pull off a joke with a firecracker on an Austrian bloke. Didn't really work out so well though. Firecracker made a bit too much of a bang.

Austrian chap went by the name of Ferdinand or something ...

I just got back from pulling a good prank. Me, my bud Chris, and two ladies got slurpees and chocolate milk and pelted our old gym teacher's house. The thing is... we do this about once or twice a week! He must have mental problems by now.

We took all the wheels off an old school bus once. Poor Carterton people had to wait.

About ten years ago, me and one of my friends tied my french teacher's car to the cover of a manhole with a rope by the stud for the bumpers. I never saw him back-up with the cover but it would've been so funny.

Sometimes the simplist jokes are the funniest.

We had one way over educated snob in our office. The kind of person that if he dropped a paper clip, it was beneath him to pick it up. He'd just wait for the cleaning crew to do it.

We'd go into his office and slightly untwist one of the Florescent light bulbs above his desk. Just enough to make it flicker or go on and off. Of course he was way too important to check it himself so he'd call building services to fix it. Since our company didn't own the building and building services was all union, they would never respond in a timely fashion. We'd wait for him to leave his office, then twist the tube back into place. The building services guys would come and find nothing wrong and make fun of the "pole up the *ss college boy". Repeat, Repeat, Repeat, Repeat.

Now after about 5 times, snob boy is getting real indignant and starts accusing the building people of total incompetance. Union boys don't take that kind of stuff very well. Especially since nothing is ever wrong when they check.

Eventually we overhear the union boys laughing and bragging about shutting off all the AC vents into his office, changing a few of the locks on his filing cabinets, leaving food scraps to attract vermin, and generally ignoring any of his calls. His reputation was made for years.

Yes sometimes the simplist jokes are the best.
Especially when you can count on everyone playing their roles.

Probably I'm too harmless.

Once I betted with someone that he will forget doing something he promised to do the week after. I won. I bet only if I know I will win.

During my social service I worked in a hospital chaplaincy. After an oecumenical service of the chaplains (some ten persons) it was planned to sit together and have some drinks and some food. Everything was prepared, but as awfully social as the chaplains were, they all decided to go home. Outdoors, they started chatting over some business things or so. With me there was another guy doing his social service who came with the BMW of his parents and even in a hurry he didn't dare to leave the place under the eyes of all those chaplains with their VW or similar cars. I promised him to help, went to the chaplains and (after some polite waiting) I asked them in to have the drink, the food. They left within 30 seconds.

In high school, my friend Jaime was always getting into trouble with the rules, so he could commonly be found working for the school's Maintenance department to pay for his various crimes. Over the years, he became good friends with the Maintenance workers, earning enough trust and working enough that they gave him his own key to the Maintenance building.

A few weeks before graduation, we used those keys to get into the Maintenance department well past midnight on a school night. From there, we stole the keys to several dozen school busses and began our work.

Our's was the typical private high school, complete with a tree-lined quarter-mile entrance drive. We parked the stolen busses parallel and across the road. We also chained some of them together.

And then we hid the keys.

In college, thus far, we've tied an entire wing's doors together at 4AM, so nobody could get out. We've also done a few other childish pranks, including setting the fire alarms off in the three biggest dorm buildings at 4:20 AM and dumping a big case of laundary detergent into a nearby fountain.

Next year, I plan on hitting the clock tower. Most modern clock towers are run with computers and speakers, not bells. Thus, a few changes in the files and the entire campus will be hearing "Dueling Banjos" on the hour, every hour.

PRANK THAT BACKFIRED.

Slow day at work, boring staff meeting, even the boss didn't attend. We all decided to forward all the phones on the west side of the building (about 150 phones) to his extension. We figured it would keep him out of our hair.

So at the end of the day, a few of us stayed behind and forwarded all the phones we could get to.

Next morning, our boss had a family emergency and had his phone forwarded to his VP's secretary. At about 8:30 her phone started ringing and didn't stop for about 90 minutes, until she figured out what was going down. (yes 90 minutes, she was as p*ssed off as she was slow) Fortunately they could never prove who did it, but of course I was always on top of the suspect list whenever anything devious occured. The VP called a departmental meeting to rip us up and down about all the lost productivity. He stared at me the entire meeting. While I was able to keep a straight face, most of my partners in crime could not. Even that didn't sway his suspicions from me.

Have I ever mentioned I've never done anything sick like that (prank as such, you sick minds)?

Does this qualify as a prank?

There was once a man in our office who was the laziest executive ever to grace our halls (one of those types who somehow arranged for a lot of his work to be done away from the office). One week the bosses were out of town on a convention/holiday and I knew that the time spent in the building for Mr. Slacker was going to be short.

So I formed a betting pool, open to all employees: "How many hours do you think Mr. Slacker will actually be in the office this week?" It was $5 to enter, we had 22 entries and the winner guessed correctly @ 24.5 hours.

I was found out of course - I didn't exactly try to hide it, really, but what could he say? I'm the bosses son.

He was gone relatively soon after that, but on another matter entirely.
