Can we all agree that an office job at an omnivorous, faceless corporation is pure evil that’s dangerous to anyone’s health? We can? Good. Then, we can probably also agree that most of the time, it isn’t the foosball table or the one-pizza-for-whole-team Fridays that make it bearable, but rather the shared moments of humorous outbursts with and from your coworkers.

“Plugged in a spare USB keyboard into my co-worker’s desktop. Would randomly hold down the shift key when he was entering his password, lock his terminal when he turned around to talk to someone, or tap the windows key while he was typing.
I’m not good at not laughing. I managed to hold it in for 4 days until he finally lost it and started smashing his keyboard and unplugging all the USB cables. He got to the one for the extra keyboard, looked around, then yanked on the cable HARD, and the spare keyboard skipped across my desk and slammed into my cube wall.
I laughed so hard I cried for almost 15 minutes.”

“Not sure if this will apply, but I was working for a telemarketing company at the time. I was the new guy and they gave me a “lead” to call that was a funeral home.
The name… Myra Maines… my remains… I called a funeral home and asked for my remains. They got me.”

“I’m a funeral director – I’d have loved to get a call like this.”

“I worked as a secretary, and there was this motivational poster of an eagle in the office with an American flag behind it that said “FREEDOM.” It was really annoying to stare at all day, so I put googly eyes on it. No one noticed for months, and it brought me joy every day.”

“Someone took the ball out of my mouse once, late at night when I had a deadline. I just took someone else’s ball, used it, then returned it. The next morning when I came in, I very loudly announced that someone castrated my mouse and I needed a new mouse.”

“I have a coworker who folds up a blanket and sits on it. When it gets cold, she shakes it out and puts it over her shoulders. So after she left for work, I unfolded it and filled the inside with hole punch dots. It took three weeks until she finally made it snow inside”

“Any time we get a new person, we hand them a plastic bag and tell them that we need an air sample to send to corporate. We tell them to go around the store with the bag open to get air from all parts of the store. Watching the new person walk around the store while flailing a plastic bag is classic.”

“I once hid $1 in pennies in my coworker’s cubicle with a note letting her know they were there. I put them in every little crack, crevice, file, book, whatever I could find. I hid them, behind stuff on her corkboard, in her calendar, etc. I made a few of them really easy to find, so she basically got hooked and couldn’t stop looking for them. She found 97.”

“One of my Tech Supervisors won the leadership award for the quarter which includes a lovely headshot for the slideshow. He hated this photo, which made me contact the company photographer and get a copy.
I proceeded to make ~200 copies of various sizes to plaster around his office. No surface was safe. I took apart his fan and taped little ones on each blade. One on the phone receiver, under the chair, inside the lamp, and basically wallpapered his desk with photos of himself.
My favorite was the three-foot poster size cut out I made to take his place at meetings.
It was three years ago and he’s still finding photos.”

“Finally a thread I can contribute to. One of my colleagues is a very funny guy and often pranks some coworkers by changing wallpapers, etc.
Once he wrote a little note to one of his colleagues:
‘Dear Ms. XY, Mr. Bear (actually a last name in Germany) called you when you were away, can you please call him back? Here is his number: 1234567890’
He gave her the number of the local zoo. She was so confused that she asked for Mr. Bear several times before she realized that it was a prank.”

“I had a coworker who hung a model plane by a small paperclip chain from the ceiling over his desk. I lowered it by adding a single paperclip to the chain every Friday night. It took months but eventually, the airplane was so low he hit his head on it and just stared at it confused.”

“At a previous job, we took turns with an on-call phone. I got it one week and found the previous coworker (D) hadn’t signed out of Hangouts (which we used company-wide for IM). We worked in a cubical farm sort of environment, and D sat next to C, though sort of back to back. They were pretty good to work bros, but not especially close.
I waited until both D and C were on phone calls, and messaged C (but it looked like it was coming from D) ‘Hey, my neck is hurting. Would you mind coming over here and rubbing on my shoulders?’
I was about 5 rows over when I hit send, but we all clearly heard C say ‘Excuse me?!?'”

“One of my favorite harmless pranks is to print out pictures of whatever you want (I like to choose pop culture icons like George Costanza or something) and cut out the heads and tape them to your co-worker’s pictures of their family and friends around their desk. Most people get a laugh out of it.
Bonus if you pick someone that the co-worker is always being told they look like. Double points if they hate it when people say that.”

“I wrote ‘You’re Welcome’ on a tiny piece of paper and taped it over the sensor on the bottom of my co-worker’s computer mouse. It was hard not to bust out laughing as he plugged/unplugged, rebooted, and checked the Windows settings before finally looking at the bottom of it.”

“Get a duplicate of a coworker’s favorite drink or coffee mug, and when they get up to use the bathroom, switch their drink for the frozen one.
I did that to a coworker who didn’t have much of a sense of humor. I thought he might get mad at me, but he didn’t even realize it was a prank. He just turned up the thermostat.”

“My mom is a software engineer for Southwest Airlines. One of her favorite stories is that her entire team got together and pretended to have this huge error that they couldn’t figure out called “ID10T” (read: I D ten T). Their manager spent a while going around asking about the error. When someone finally wrote it out for him, he had a good chuckle about it. Pretty harmless and it got a good laugh from the entire office.”

“I worked with a few people that would be ‘hunt and peck’ typers. Just switch the m and n keys. that can cause headaches for people.
Something I still do, I’ll write a time like 3:30 and circle it on a small piece of paper and slip it into a coworker’s pocket. that will leave them wondering what they are forgetting.
Both are pretty harmless and you can’t really get into much trouble.”

“Work as a firefighter, one time someone ran a drip set (IV bag) through the drop ceiling into a neighboring bunk room, directly over the head of another firefighter, when everybody fell asleep he barely opened the line up so it would drip one drop of water every 45 seconds or so, directly on to the sleeping firefighter head.”

“Worked over the summer back in like 2002 at a car dealership, I heard that an older salesman had just been fired for selling a lady a new Subaru, she kept insisting that the car have 6 cylinders (to be fair Subaru flat 4s were almost as powerful as V6s back then) and after her resisting he finally told her just to buy the car and they will put in the extra 2 cylinders later.”

“Mid 90’s, cleared a friend/co-worker’s cube out while he was on vacation in Europe, and sealed it off with Crime scene tape. When he came back, called him into our manager’s office and told him a fairly elaborate, extremely believable story about how the office had been raided, and everything from his cube taken into evidence.
Freaked him out so bad that we had to come clean with him almost immediately.”

“I worked in an office and would remove all but 3 or 4 staples out of my coworker’s stapler every day since he left before me. We often staple a stack of documents so you would hear him at his desk:
staple… staple… staple… click, click “DAMN IT!!”
He thought the janitorial staff that cleaned the office at night was stealing his staples. I never told him it was me.”

“Two things we did when people were out for a couple of weeks:
Grew chia seeds in his keyboard so it was a small field when he got back.
Another time (different guy) we just started leaving any trash on his desk (things that wouldn’t smell) then say before he came back we got some gift wrap and wrapped up the whole cube. The bonus was we hid a six-pack of Smirnoff ices in the rubble.”

“I used to work at Sun Microsystems back in the day. We were renowned for our April Fool’s pranks.
One year, I was part of the team that turned a director’s office into a farm, complete with livestock. Another year, we wrapped a building in plastic. Another year, we ran a giant arrow through a building.”

“My colleague went on holiday for 2 weeks. Giving us enough time to attach all of his paperclips together in a giant ball. Every time he wanted a paper clip he had to untangle each individual one. He would occasionally forget it had happened and would randomly hear a sigh as he had to fight to free his paper clips.”

“My buddy had this hand lotion on his desk that he used every day soon as he got into work. I found the same brand/bottle and bought it, emptied it out, then filled it full of mayonnaise. Made sure it was the same weight as his current lotion before making the switch, just in case.
He came in and used it! I screwed up and started laughing way too hard and had to fess up, who knows how long he would have kept putting mayo on his hands before realizing something was up!”

“I had this prank pulled on me. This was in my first job, about 12 years ago. We weren’t allowed to share music files via work email, but my work buddy begged me to anyway. I’d only just sent him some song he asked for, when I got a pop up from an anon sender basically saying: “this is IT, we observed you sent, blah blah, blah and we’re locking your account”. I flipped out, thinking it was for real, and then I hear him laughing a few cubicles away. He sent me the pop-up. I totally fell for it.”
