"A Tiny Piece Of Masking Tape Over A Coworker's Mouse Laser": 35 People Share Genius Yet Harmless Ways To Prank Others

My grandpa does this thing where he stops in the busy street and starts staring into the sky as if he’s seen something amazing. It doesn’t take long for other people to stop and stare too, once he’s reaches critical mass he quietly slips away chuckling to himself.

Edit, he’s in his 90’s now but when he was a teenager he was a bit of a young tearaway and had a pet monkey, which is weird considering this was the UK.

Edit 2: holy c**p this blew up overnight. And on my cake day too!

Buy a set of “Voice Activated” or “Motion Activated” stickers from Amazon, and the possibilities are endless

Every other week or so I'd change which side my coworker's drill's belt clip was on, 2 screws and 30 seconds for a maddening payout. Idk if he ever caught on, as he sadly passed away last year.
I got a huge kick out of doing it though. Might bring that one back as most of us share the same brand of drill. He got a great one on me.
Every day or two he'd hide a Magic the Gathering card in my toolbox, never the same spot twice. Genuinely made me mad when I'd pick something up only to see another card hidden beneath.
Eventually I had enough cards to completely cover his locker door inner and outer, he never took them off. Even cut out cards to fit the vents on the locker. I spent a good hour or two on my day off making it. Proud of that one. RIP Chris. Pranks haven't been the same since you left. Your locker still remains covered in Magic cards and nobody has questioned it to this day.

Senior prank at my high school a few years ago, they let 3 chickens lose: numbered 1, 2, and 4.

School took forever looking for the 3rd chicken

Occasionally I get Christmas cards sent to my address meant for the previous homeowners, wrong address etc. I take these cards and mail them to my friends and family with their correct names and addresses etc and with their return address. I can imagine them sitting around their table scratching their heads wondering who the hell the O’Reilly family is, in a family picture all dressed up in their Christmas garb sending them a Christmas card. A couple times I than learned that the next year out of courtesy, my relatives would then send the unknown family a Christmas card from them, and than that family is like who the hell are these people.

I put a tiny piece of masking tape over my co-worker’s mouse laser on April fool’s day one year, wrote “April fool’s” on it. He troubleshot every single thing except examining the mouse. He eventually called IT who simply turned the mouse over and pointed it out to him.

My grandpa glued a quarter to his driveway near the sidewalk and sits in his living room and watches people try to pick it up. I didn't know this till I found a quarter in the driveway one time.

When in an elavator with strangers (or just walking thru a lobby) casually look down and say "oh wow they really did a good job getting the blood out".

When someone knocks on the public washroom door you are in respond with come in!

I do this every so often because it's kind of a game to me to see how long I can keep it up till the person catches on.

I repeat the last word the person says in question form.

Example:

"Hey, me and Jenny are headed to Jim's Pizza Hut."

"Jim's Pizza Hut?"

"Yeah, you know the one on F street."

"F Street?"

Over there near the harbor with the big carousel."

"Carousel?"

"Yeah, you know the one you went with me and Jane."

"Jane?"

"My girlfriend."

"Girlfriend?"

"Ok, what the f**k is wrong with you?"

Once they call you out and have caught on the game ends. I've carried on a conversation over an hour once doing this. It's really awesome when the person you are doing it to has gone through this a few times with you.

My daughter has gotten me a few times herself and she'll laugh on and off for the day at my expense. Her husband has called me an a*s for teaching this to her a few times too.

My son can make dolphin sounds to perfection. We were on a dolphin excursion and he would randomly do the sounds. People kept looking over the sides to see the dolphins. He also confused the operator because he kept looking around for dolphins. One of our best family vacation memories.

When I order coffee and they ask for the name I say “Green. Like the sky.”

My personal favorite is: Sit down on a park bench next to someone. Slide a manila enevlope with a picture of a random person from the net to them and say, "It has to be done by Friday and it has to look like an accident." Then get up and walk away quickly.

When you shake someone's hand, move yours left to right. As they do the traditional up and down, a hilarious circle ensues.

Say "no pun intended" after a sentence where there was clearly no pun.

Edit: For PSA

Hide something around their house. My weapon of choice was tiny rubber ducks.

Open a drawer? Duck.

I need a spoon. Duck.

Lovely picture of their wedding with a nice frame? Duck on top.

Charging box? Duck.

Bubble bath? Duck.

Seldom used shoes? Duck.

Winter coat pocket they won't use for months? Duck.

Its ducking delightful how much mileage you can get out of tiny ducks.

PSA: Be extremely cautious in the case of households containing animals and small children. Both like putting little things in their mouths and other orifices so might be best to avoid Ducking these individuals/ensuring things are definitely out of reach.

When you're talking to someone, just keep handing them random items. They'll just keep taking them without realizing it.

This one is harmless but occasionally can drive someone mad.

My mom has a bunch of framed family photos hangin on a wall. One day I was visiting I took them all down and scanned them with a little hand scanner. I photoshoped small changes on them, removed some people from some photos, added a couple of celebrities in the background, etc, print them out and replaced them a few days later.

I can't forget her face when she realized it was me and she was not losing it.

My friend was logged into his twitter on my tablet so I kept changing his profile picture to a banana.. he thought someone hacked him and tweeted about it.. I replied to the tweet using his profile.. it got so bad he was arguing with himself on twitter.

When I was a corrections officer we had a guy who worked with us who was kind of a d**k to everyone, and he was computer illiterate. We took a screenshot of his desktop and moved all of his icons off of it so it looked legit but nothing worked. It took him an hour before he finally called IT and they figured it out pretty quickly. He wouldn’t talk to any of us for about a week.
