The copying room Karen who was of course this religious nutcase was territorial and every day she’d claim the copier for 20 minutes. This was in a faculty room setting where everyone is scrambling each morning. I finally had enough. Got there before her, pulled a ream of paper and made 500 copies with “Satan Owns Your Soul” in sharpie. Placed these back in the copier. When she ran her copies everything came out with this on it. She went home and took a few days off. I enjoyed those few days immensely.

One of my best friends was working as a section manager in a retail store. He bought a box of like, 400 rubber duckies off Amazon and started leaving a single one on his boss' desk at random times. Never said a word to her about it, and would pick odd times to do it to throw her off the scent - like if he came on an off day to shop, he'd sneak one in. He'd come in 30 mins before his shift started to do it. He'd stay late to do it.

He did this for *at least* six months before he got promoted and got a transfer. On his last day of work he walked into her office with the box of the rest and turned them upside down on her desk.

She hit something like a combo of hysterical laughter and sobbing - "OH MY GOD I THOUGHT I WAS GOING INSANE".

6 months after we broke up I realized somehow my Spotify is connected to my Ex’s Alexa. So now sometimes at 5am I accidentally on purpose connect to it and play “Top 50 Most Annoying Songs of all time”. I see the song stop and then I press play again, we do a back and forth until he gives up.

That’s what you get when you f**k your flight instructor, Brent.

One time, my buddy Steve was at my house and the phone rang. The call display showed his number, so I knew it had to be his roommate, probably looking for him. I picked up the receiver and immediately asked, "Hi, is Steve there?" There was a pause, then, "Uh... no, he's out." Just as quick I said, "Cool, I'll try again later. Bye!" and hung up. It was probably a good minute before she called back to call me a bastard.

It was only a few weeks, but a supervisor on a construction site I worked on was complaining about the birds in front of his office. That night I went to a pet shop and bought a big bag of birdseed. I hid it nearby, and when the coast was clear I would scatter a couple of handfuls. It took a few days, but more & more birds started stopping by to look for food. Had over 30 pigeons out there one morning when he came in. I let him in on what I was doing one day when he’d pretty much given up and was throwing old bread out for the birds.

He later asked me to pick up another bag of seed, as he’d taken over throwing out seed and ran out.

Back in the day I used to cold call in a s****y sales job and eventually I got bored.
When I would ask for Mr Smith, and they would say he's not here can I take a message?

I used to leave messages.

"tell him he was right, it's not going to fit"

Or,

"tell him it'll have to be the blue one, the red one isn't available"

Or,

"we can't do 7o clock because the cat isn't well"

If they queried it any further (and they usually didn't) I'd say he will know what it means.

I like to think I've left a legacy of people scratching their heads for days.

My brother in-law upset my younger sister. My older sister decided to teach him a lesson.

For the next several months he began receiving the most random items via The US Postal service with no return address, no letter, no explanation.

What was sent? Sawdust, pocket lint, acorns, twigs, leaves, sand, amongst a dozen other harmless items.

The kicker? My sister did not send all of these items from one location, or even just herself. She got her friends and close colleagues involved, due to the nature of her circle the postmarks originated in locations from across the US.

He received random s**t from something like 28 different states and Canada. Eventually started to freak out and wanted to call the police and the FBI before they finally told him.

My brother in-law learned to compromise on home decor decisions going forward.

When I was about 14, and older brother was 17, he was a real violent d******d. He made my life a living hell. He would take deep naps every afternoon. I would go to the kitchen and get the bottle of Wesson veg oil and put a tablespoon or so in the cap. I’d sneak in his room, and with a Qtip I dispensed tiny drops of oil all over exposed skin. He was a very pretty lad so to turn into a pizza pie all over his face, neck, back, arms was enormously distressing. He went on multiple medications. I probably did this for about two years. You want to beat up a girl who is half your size on the reg? He was bigger but I was smarter 🤣.

During my first semester at college, my roommate always had girls over in our single-room dorm, forcing me to sleep in the common area and shower at the gym. As revenge, I started putting a Jolly Rancher candy inside our bathroom showerhead. Every morning, they'd shower together, but when rinsing off in the shower, they'd be left with a thin layer of sugar on their skin and in their hair. The girls stopped coming over because they all felt sticky and gross throughout the day, leading them to attribute that unclean feeling to my roommate. By the beginning of the second semester, he couldn't get a date (which was 99% of the reason he was in college), so he dropped out. I had the dorm room to myself for the rest of the year. The first change I made was removing the remains of the Jolly Rancher from the shower head.

I delay my voice when I see the same supervisor at work. I mouth "Hey" and then say it without moving my lips after.

He's asked the other lads if they've noticed and they act dumb but when I do it to him I can see he thinks he's going mad.

Hes asked the boss if he's noticed me doing it and he hasn't because I only do it to the idiot supervisor. Drives him nuts and makes my day feel better.

My colleague went on a stag do with a friend of mine. Topline - absolutely NOTHING happened. My mate said it was very tame and no controversy.

Anyway upon his return he walked past me and I said "I heard what happened at the stag."

He immediately went BRIGHT red and said "WHAT HAVE YOU HEARD."

I simply replied: "don't worry your secret is safe with me" and went on with my day.

He has spent the last week demanding to know what I know whilst going up to colleagues and asking if they'd heard me say anything.

Further context, I'm known as the quiet one in the office which made it much more believable.

Way back in the days before tvs would display every little thing you could change the volume and brightness without it registering on the screen.

My friend and I would take the remote while his little brother was watching the TV and very slowly turn down the brightness. Like 1 click of the button every 30 seconds. Eventually it was nearly black and he could never figure out what was going on. We would claim that we could see the TV fine.

Picture this, 16 year old boy comes home from an exhausting day being a 16 year old boy, heads to his bedroom, flings himself on his bed and reaches for the tv remote. He presses the button, then presses the button harder- nothing!

The fun starts here because I’d put a small piece of black tape over the infra-red receiver on his TV. So nothing to see on the remote itself, this was essential because I knew he would suspect my involvement immediately. His first thought was that I’d turned one of the batteries around, not bad reasoning I thought. So accusations and denials fly, new batteries are located and inserted but alas the problem persists.

It was such fun listening to his frustration and hearing him having to get out of bed to change channel etc. I left it in place for several months, then after present opening on Christmas Day,I told him I had a little extra present for him in his room. He watched as I removed the little bit of tape. Marvellous!

He’s 29 now, ah such fond memories.

In days of yore my boss had a desktop push button landline phone. To mess with his head if he'd been especially annoying we'd change the button covers on his phone. So instead of the buttons going 1, 2, 3 etc horizontally we'd change them to vertically.

He never spotted it, as the 1, 9 and 0 were always in the right place. Drove him nuts and we'd hear him cursing and swearing when he dialled wrong numbers. The following day we'd change the numbers back and so forth. He called out the phone repair chap a few times but we made sure to change it back before he came. He was an a**e and always very volatile and sweary. This gave us great pleasure.

Top tip, don't mess with your troops, they will get revenge.
