A friend once crucified a blow up love doll to the tree in my front yard. It was kind of disturbing.
I’ve seen that one before. Insane!
When I was in college, we often had to stay overnight to complete some projects in time. One night a bunch of guys cut a hole in the ceiling and completely filled our prof’s office with packing peanuts. You should have seen his face in the morning when he opened the door and was avalanched by styrofoam bits. 
One more from the fire station. I got Hubby a nice Starbuck’s insulated mug for his birthday one year. He, of course took it to work. After about a week it disappeared.
Well, two weeks later, the cup returned, covered with travel stickers and accompanied by a stack of photos of the cup in various locations.
It first went to flight test, then to DC, pictures showed it at the J Edgar Hoover building, and a couple of the memorials. Then on to Hawaii… someone was on vacation in those two places, so they Fed Exed it to the new locations.
His cup had a better vacation than we did!
Many years ago I heard of a similar prank - may be an urban legend for all I know, but it involved a garden gnome that disappeared from someone’s yard and returned a year later, to the day. When it came back, it had photos of itself from all over the world.
Sadly, the best workplace prank I’ve pulled wasn’t that inventive. I used to work in a place where we assembled mildly radioactive components and were required to wash our hands before leaving the room. My friend always ran to be first, so one day I had the lab assistant, whose desk was near the sink, tape down the handle on the sprayer so that my friend got soaked when she turned the water on.
Almost forgot this one - when I lived in Atlanta I shared a house with 5 other people. One night one of my roommates and I were under the influence and decided to play a joke on another of our roommates. He was asleep, so we snuck in his room and got all of his shoes except for one pair of sandals. (This was in January) We tied the laces together and threw them up into the tree in the front yard. We were asleep when he woke up, and awakened to hear him yelling about not being able to find his shoes. He decided to wear the sandals with socks rather than be late for work, and walks out the front door to find out where his shoes were.
We never admitted who did it.
Two from a company I used to work for-
Once, we shrink-wrapped our boss’s office and everything in it. Purple shrink-wrap.
And one time, we rebuilt our CFO’s office in the mens room- desk, chair, credenza, pictures on the walls, everything (so he would have his back to the urinal so the boys could have some privacy while they peed!). We even hooked up his phone. Replaced the restroom door sign with his. He was a funny guy, and played along. He worked in that mens room all day.
At a former workplace we had a marketing director who was sweet, but a bit obnoxious in her great enthusiasm for things marketing. Therefore, we, the graphic design team, tortured her mercilessly.
In one instance we removed the receivers from all three of her office phones and replaced each receiver with a banana (sticking the curly phone cord thingy into the banana and setting it on the receiver cradle.) Since the phones were yellow, she didn’t notice the bananas until the phone rang . . . and she ran from phone to phone, screaming as she found they were all bananas 
She also had a habit of removing her heels in the afternoon and kicking them under her desk. She went to an informal meeting sans shoes one afternoon and we dipped them in acrylic paint, made shoe prints up the wall and across the ceiling, then super-glued the heels and toes of the shoes to the acoustic ceiling tile. She was unamused when she tore off the shoes and a chunk o’ ceiling came with them!
I love it!!!
Hilarious!
Whenever I’m at my mom’s work I’ll tape her stapler together and write her a bunch of memos about the CPS reports, nothing major.
Oh oh oh! I just rememberd this as I was waiting for the page to load.
I know this family who has a mom that works at a place where she needs an I.D. for everything and has to show it to security guards whenever she’s entering an area. One day her sons carefuly superglued a picture of a baboon to her I.D. without her noticing and apparently the look on the security guard’s face was priceless when he looked at at her I.D. card.
In college, there is the tradition that if you leave your door unlocked when you go out, your room will get Tharunkaed. Tharunka is the student newspaper and everyone from the floor would pitch in to get back issues of the Tharunka, rip out the pages, scrunch them up into balls and completely fill your room to the ceiling with it.
We did something similar to one of our buddies who got married in the Canal Zone back in the early 70’s. He went off for a three day honeymoon with the professed intention of being back Sunday morning at 10:00AM. About 10 of us (as best I recall) went to his apartment armed with stacks of old newspaper and empty coke cans. I had brought a few other items as well.
First we filled his bathtub with Jello and then turned off the water heater. We also put plastic wrap over the toilet bowl but under the seat. Then, after putting a pair of my wife’s panties into his underware drawer, we stacked the empty Coke cans against the kitchen door (which was the one most people in those apartments used since it was at the top of the stairs) and filled the rest of the apartment with crushed newspaper to the ceiling, closing the front door behind us when we left.
Charlie and his new bride didn’t get home until 10PM and I wish I could have seen his face. Apparemtly such jokes weren’t funny to him after dark, although his bride loved it. Charlie, after being buried under falling Coke cans and crushed newspaper, was kicking the stuff and loudly cursing when a Canal Zone Policeman going to work asked him what was wrong.
Livid, Charlie dragged the man upstairs shouting “Look what they did! What can I charge them with?!” The laughing cop replied “I don’t know, but don’t leave that stuff in the street or I’ll have to arrest you for littering!”
In college, we somehow found ourselves in posession of a spool of tape with little yellow smiley faces on it like this one :). We cut out hundreds of them and placed them over each of the keys on a roommate’s keyboard. We changed all his icons to a smiley face, changed the color scheme to yellow and black, and set a custom font in which all the characters were smiley faces to the default system font.
He had a fun time using another computer as reference to change it back. He needed the other computer to figure out how to read all the dialogs, because the only thing he could read on his was :):):):):):):):)
In The Dilbert Zone, there was a section on office pranks. One was to buy a cheap pager and set it on vibrate. Then you wedge it into the padding of the victim’s chair and call the pager’s number throughout the day.
I once got an email awarding me something or other for outstanding service. The prize was an Executive Cup Holder, and it had a “click here to receive” button. It made the CD drive pop open.
I believe that prank was in a movie. (Amelie?) The daughter stole the gnome from her father’s garden and sent it with a flight attendant friend all over the world. The “gnome” sent back pictures to the dad. I believe the subplot was that she was trying to convince her father to get out and live a little since her mom had passed away.
Not an office prank, but a lover’s spat…the tenants before me in my old Berlin apartment had had a bit of a tiff and the one roommate left and other stayed in their apartment and in a few weeks, got a new lover.
The one who left was a bricklayer by profession.
In the middle of the night, he completely bricked up the doorway to his old apartment, where ex and new boyfriend were living. By morning, the cement had gotten nice and hard and the wall was solid.
The guy in the apartment had to call the fire department to get them to tear down the brick wall…and the bricklayer was later arrested.
The story made all the local newspapers with the headline “wall torn down” (before the Berlin Wall actually was torn down.)
Before Amelie at least, I’ve seen that happening. It’s a popular one with RAAFies (Royal Australian Air Force members). When you’re posted overseas, or going on leave somewhere you knick someone’s favourite coffee mug or little desk/locker icon and take it with you, periodically posting back photos of it in various (and sometimes illegal) situations. I’ve seen some of the photos, from when I used to go to work with my dad.
On another board I used to post on, we had a similar thing going. It was a stuffed toy, and it’d be sent to various board members over the world, going to meets and parties and sightseeing, and the photos’d be posted on the board. That was kind of fun, too.
Two parter, joke was on me:
- My “best friend” Don calls my workplace while I’m out to lunch. Gets the secretary(Sarah). Asks for me. She says I’m not in, can she take a message. He says, “Sure. Just remind him it’s the first of the month.”
“First of the month?” she asks, a little confused by the cryptic message.
“Oh, right,” he says, and explains the situation.
The NEXT scene is this:
- I come in, and walk right by her desk. She says nothing until I am at the far end of our cubicle farm. So she has to shout, and all 20 people in there hear every word of the conversation… And she goes:
“HARRY, DON CALLED WHILE YOU WERE OUT!”
“WHAT’D HE SAY?”
“HE SAID IT WAS THE FIRST OF THE MONTH AND YOU OWE HIM TEN DOLLARS!”
“TEN DOLLARS? FOR WHAT?” I say, totally confused.
“HE SAID YOU PAY HIM TEN DOLLARS A MONTH TO BE HIS FRIEND, AND THIS IS THE FIRST OF THE MONTH, SO YOU OWE HIM THE TEN DOLLARS!!”
(I ain’t changing no names to protect nobody!)
