Office Mischief and pranks!?!?! tell me what your guilty of!

I wasn't a part of this, but it was hilarious. A colleague of mine keeps a stuffed bird on her desk, and one day it went missing. Everyday for 2 weeks a picture of the bird would show up on her desk. There were pics of the bird on a motorcycle, at the concierge desk at the Royal York hotel, at the lost and found in the train station.
The bird was returned 2 weeks later unharmed, lol.

LOL! This would have been hilarious at my work at the time. I had a boss who had a cherished trophy that he wouldn't let anyone touch.

ohhh so many to choose from...obvious favourite was the stapler..People get seriously territorial over THEIR staplers, and as a rule of thumb, the bigger jerk and annoying they are, the more guarded they are about staplers. I snuck back into work after everyone had left and put the staplers inside jello moulds filled with the corresponding coloured jello, and came in before everyone after they had set and placed them on the respective desks...


also, cheap nasty office-grade carpets...the day before i quit this horrible company, I stayed in 'late' and hosed down all of the carpets with LOTS of water, then scattered a TON of mustard and cress seeds...they sprouted *beautifully* overnight.

I also rigged up all the office chairs to a small generator and at random times, gave people a gentle 12 volt reminder shock ;-)

Every year around Halloween the owners mom will bring mini pumpkins for the all the sales guys, we hide the pumpkins in each others cubes, we have pumpkins floating around from two years ago. If someone goes on vacation, I will tape everything possible in the cubicle. Un-hook the cord to the handset for the phone, when they pick up it falls out. I had a guy working in the warehouse that rode his bike to work, we shrink wrapped his back and hung it from the rafters!

Connect the mouse for 1pc to the cpu of the person sat next to them and vice versa. Drives people crazy for ages before they fathom it out!

We had a lady complain about not getting her change back, it was like 32 cents....everyone in the office had to chip in $5.68 so we all just handed over $6. She INSISTED on getting her 32 cents. That night we glued down a bunch of quarters nickles dimes pennies to the floor all around her office. She was all excited at first, but then became furious after not being able to pick them up.
Same lady *****ed about only having one coffee maker in the office and that she only drinks caffeine free due to religious reasons, she was Mormon. Insisted the office chip in $$$$ for another coffee maker because the existing one cannot be used to make caffeine free if it's already been used to make regular.
We got some fake dollar bills and dropped a few near her desk one early morning...LMAO, same response as the glued coins.

A guy in the office went on vacation to Vietnam and brought back candy that looked like dog turds. Me and another guy pretended to like them but then would go on other floors and drop them at random.

Pranks calls in the office using a voice soundboard on the internet.

Work in a Jail. One of the 1st shift officers is always messing with things from 2nd and 3rd shift officers. Finally we had enough and, since nobody on 2nd/3rd drinks coffee, we emptied all the coffee out of the tub into a ziplock and hid the extra tubs of coffee. We left a ransom note in the empty tub that said "If you ever want to see your coffee again, replace our stuff and stop messing with it" Everything was replaced the very same day :-) I guess those 1st shifters need their coffee :-)

Oh the list is endless here as my work place is full of pranksters.

The best one I've done was the time a coworker left his leftover Tai food under my desk (he does this often-candy wrappers, paper towels, endless junk just to be annoying.) Well I retaliated and took the Tai food out to his car. Background here...he never keeps his car cleaned out...I mean, just full of crap kind of car. So I cleaned out enough stuff and shoved the container under his passenger side front seat, put all the junk back, and went back to work.

Needless to say, two weeks later I got a text that said "You F***ing B**ch!! Haha...My response.."Well I thought it was yours??" What was funniest about it was he was on a date with a chick and after she complained about his car smelling so bad that night...he finally put it together that something was off and searched his car.

If you've ever worked in a firm, you know there is usually one bathroom that is shared. That means if the paralegal for the Family Law Attorney decides to spend her Sunday nights getting sh*tfaced, you're going to smell it Monday morning after she uses the bathroom. Clear wrap isn't just good for wrapping up your leftover chicken breast. Pick up the toilet seat and wrap it TIGHTLY to the bowl so its invisible, tuck it in underneath the rim and put the seat back down. Nothing like a dose of your own medicine, right? Hahhahahaa

Oh I also replaced the cream filling in someones oreos with toothpaste
