Best Prank Ever Pulled?

[Bitter Clinger]

We stuffed the neighbors cat in the mailbox once. Should have seen the look on the mail mans face when he opened the box and was attacked by a pissed off feline.

Maybe that's why you're getting such crappy mail service these days...

Put a dab of Vaseline in the center of someone's windshield. When they see it their first instinct is to turn on the wipers. Makes a heck of a streaky mess. Just be aware you could be the cause of a nasty vehicle accident.

I was under age at the time. Kids will be kids. What can I say?

And for the record, my buddy and I got the worst end of that deal anyways. Apparently cats don't like being put in a mailbox. He didn't even put a scratch on the mailman when he was "released". Can't say the same for me and my friend. We almost needed another person to stuff him in the box.

In High school, a chick was extremely drunk at a party and we got her to believe if she drank water topless from the dog bowl she wouldn't have a hangover.

Chained and locked a buddy's car to a light pole in the high school parking lot so he had to call his mom for a ride home.

baseball coaches went out drinking so we secured a key to their room, put red ants under the sheets, maple syrup in their shampoo and conditioning bottles, red pepper in their pillow cases, and soaked all their clothes they had laid out and in their bags.....we ran A LOT the next day after the game, then they got us back by soaking our bed with ice water and left a huge dump in the toilet with the handle disconnected and the toilet seat taken off....nasty!

We moved one kids mattress onto the roof of a house we rented for a baseball tournament, put his hand in warm water. Double surprise in the morning when he awoke on the roof, he had pissed his pants, and we locked the window.

deflated all the annoying people's car tires at a frat party in college.

Picked up a Honda Civic when they first came out and put it sideways in a carport(2-3 inches clearance on the poles)
I had a great boss at CDOT, he was a wiseacre and was pulling pranks all the time.
He left me in charge when he went on vacation and when he got back we went to breakfast to fill him in.
We jumped in the truck he usually drove and prior, we made sure the windshield was just dirty enough to warrant using the wiper/washer.
I had rerouted the washer hose into the cab under the column.
He never batted an eye and went to breakfast with a soaked crotch.
AntiSeize or Prussian Blue on toolbox drawer pulls was always entertaining.
When I was a fabricator/welder there was always a good supply of BlackCats in my tool box.
Loads of fun when somebody is welding and has a hangover, you don't even have to light them, always better when they are welding in a truck utility body or other confined space.
Rearranging plug wires was always fun.
We had a Cuban guy at a truck shop that wasn't the brightest bulb. Good guy and hard worker but he was pretty much a welder, technical things such as wiring were beyond him.
I taught him how to wire up a utility body for a truck, turn signals, back up alarm and lights etc. He was so happy he learned it and understood it! I let him wire up one truck by himself and he did well.
I was on a truck next to him and he was checking his work, turning on the turn signals and walking back to the rear of the truck.
Every time he he would get back in the cab and try a different circuit the back up alarm would go off.
He found this terribly confusing and was beside himself double checking his work. He came over and got me, told me what was going on and asked me to check his work.
His work checked just fine.
I went back over to the truck I was working on and he tested the truck one more time. Be damned the back up alarm would go off again when he hit the brakes, turn signal etc. He was so flustered he was almost in tears.
He never noticed me sitting on top of the other truck with a back up alarm.

I got my boss this winter. I went all over the place and emptied out all the hole punches we have. Stuffed them all in his defroster vents, turned the fan all the way up. He locks his car now......

While on shore duty replaced one of my shipmates' "special" lube with Icy Hot.

One of our favorite family traditions is fvck with uncle mike at out of town car shows, seran wrap over the toilet and shower-head. Goldfish in the toilet. Buying VERY VERY large granny panties, drop them in the mud stuff them underneath the covers and remake the bed.

One of the best, a buddy was being a loud obnoxious a-hole at the bar one night, I went and bought a condom from the restroom and stuffed it in his beer bottle....he drank half of it before he found it.

In the Navy I drilled a hole into my squad leaders toolbox and put a zerk fitting in it, we had air powered grease guns, I hooked it up and left it on over night.

College:

Filled a garbage can about half full of water and leaned it on the door of the mark. When door opens...flooded.

Took a blow dryer and a bottle of baby powder. Blew the entire bottle under a door into the marks room.

Mark accidentally forgot to lock his door. When he came back everything in there was in one giant pile in the middle of the room.

Glued every item on marks desk to the desk.

Lots of silly stuff like this went on.

Automotive pranks were always fun in high school.

A ported vacuum line from the carb run down the transmission dipstick tube results in James Bond style smoke clouds, but only after they start to drive away.

A wire run from the brake light switch or turn signal to the horn relay is also fun.

Antifreeze in the windshield washer bottle is just plain evil.
