Misspelling their name in emails.

Misspell their name in emails.

Place dead batteries in their keyboard/mouse.

Do this every day for a week.

Example: Well, thats just the bees knees!

Incorrectly correcting their pronunciation.

I like to incorrectly correct peoples pronunciation.

Like theyll say beignet ben-yay and Ill say, actually, its bang-yet.

But every so often Ill actually convince someone theyre wrong.

9.

Adjusting the keyboard rest.

Whenever my coworker isnt at his desk, Ill put back onebut only oneof the keyboard rests.

So next time he goes to pop in, his keyboard will be off balance!

Also, sometimes I mess with his adjustable chair arm rests.

Ghost in the disc drive.

Not incredibly often, but enough to the point where it was annoying.

He requested a new computer, I reinstalled the .scr as soon as he left that day.

Set the screenshot as his desktop background.

On a Windows machine, go into the mouse options and enable Click Lock.

The new one will do it, too.

Or just microwave some fish.

I plant evil questions in their lectures and tutorials.

I plant evil questions in their lectures and tutorials, seeding them to students we have in common.

Ive been doing it for years, and they have no idea its happening.

I use my boss as my personal Google.

The former big boss of my oil plant works in the office with me.

Him- NO ITS NOTits 12 if you do Route A, and 10.5 if you go Route B etc.

16.

Ghost in the mouse.

Once I plugged in a wireless mouse into their computer without them knowing.

And a few times a day I would just jiggle the mouse.

Just enough to hear them slamming down the mouse and muttering under their breath and Id stop.

This went on for several days.

Sometimes Id stop by to chat, and I would bring the mouse.

I used to mess with a former coworker that was always rude to me.

Changing times on the microwaves.

We have two microwaves in the break room that somebody needs the time to be the same on.

I used to change the time on one by twenty minutes and wait for them to fix it.

Now I change it by one minute every day until they fix it and I start over.

I have a few coworkers (myself included) that run on Post-It notes.

Seriously, some of our desks look like that Pepe Silva scene inAlways Sunny.

That said, I take advantage of this.

I do fairly well at copying others handwriting.

Ill do my best facsimile of something innocuous or mildly ominous and place it among their other post-its.

My notable favorites were: Ask Linda about the bees.

Scotch tape on the mouse.

Put a strip of Scotch tape on the underside of their computer mouse.

They likely wont even notice, just be subconsciously frustrated.

Add an additional strip each day until they notice.

21.

Adding a ridiculous title every time they bang out their name.

Change their autocorrect prefs in Outlook so when they punch in their name it adds a ridiculous title.

Adding 1,000 paper sheets to my HR directors messy desk.

Our old HR director was notorious for having a messy desk.

Every morning hed come in and 10-15 more sheets would be added to the mess.

It took a long time for him to suspect something was up.

Crush on the desktop.

Then I tabbed back to whatever program she had been using so she wouldnt notice right away.

Guy arrives for the meeting.

In a way, that prank almost worked too well.

Staring at a spot slightly above their eye.

I just keep handing them random items.

99% of the time theyll keep accepting.

Setting a screen shot as their wallpaper.

I find it amusing listening to their call to IT.

Winston, my imaginary cat.

My coworkers think I have a cat.

Ive named him Winston.

I even have a photo of some random cat on my phone in case anyone inquires further.

I dont have a cat, of course.

But I do chuckle to myself at the thought ofWinston, My Imaginary Cat.

Whistling Christmas songs in June.

I whistle Christmas songs in months other than December.

Just the first few lines once or twice an hour.

Give it a few hours and theyre questioning why Jingle Bells is stuck in their head mid-June.

Gradually changing the sensitivity configs on their computer mouse.

Messing with the bathroom code.

So our mens bathroom had a code to get in 123.

For months whenever I entered or left the bathroom I would enter in a number in the keypad.

If anyone went in after me, the code wouldnt work the first time.

They actually had to remove the code after about a year.

Gradually moving the desk divider.

Since I moved beside him two weeks ago Ive been moving the divider a centimeter towards him each day.

Were at 13cm and he hasnt noticed yet.

I have to shift his monitors soon though so that will be interesting.

Manila envelope full of glitter.

I sent a coworker I loathed a manila envelope full of glitter.

She promptly tore it open.

That was two years ago, and she still finds glitter everywhere.

Our lil office fairy.

For a while my favorite thing was to unplug their mouse & put a sticky under the mouse sensor.

Was great when people plugged it back it and it still didnt work…

My department is pretty small, so when we fuck with someone, everyone is involved.

About a few hours into her shift, shit got real.

See, the rest of her desk was seemingly normal.

There was an instant messaging group where we planned on real time behind the scenes.

This started subtle, and got more and more ridiculous as the day played out.

We have yet to top this one.

Framing a pen thief.

In my first job out of college I worked at a small tech company.

One of the bosses was a very sweet woman.

She had borrowed pens a few times and forgot to give them back.

I began to steal every pen in office over the course of a month (100+ pens).

I made sure that the nicer pens that people associate as theirs were always specifically found in her desk.

She would always deny it only to find them right there.

Christmas rolls around and we have the company Christmas party.

When its opened, the room explodes with laughter and accusations.

I add the Chrome extension cenafy to other people computer and turn their speakers up.

When theyre browsing the internet…. AND HIS NAME IS JOHN CENA.

You cant exit out of it till its over too.

Many years ago, I had collected money from the staff for aholiday partyand left it on my desk.

I went to the bathroom and came back to find the money missing.

I was freaking out about the missing money searching with my boss who was disappointed I left it unattended.

I went online and bought something called the Annoyotron.

She would go wide eyes and say OMG yes!

I cant figure it out!

Its driving me crazy.

I spilled the beans and apologized to the person she shared a cubicle with as she was collateral damage.

She never fucked with me again.

He was apparently super pissed about it.

Blamed my April Fools prank on a different coworker, too, which made it even better.

Very tiny printouts of a coworkers head.

I have very tiny printouts of just his head.

I sneak them all over the office in inconspicuous places.

This has been going on for 2 years.

He still doesnt know its me.

We have this old crotchety hyper religious nut at my job.

Very annoying, sits on her butt all day.

I put a remote-control speaker, loaded a 30kb sound file of demonic voices whispering.

When she starts hearing and looking around, I cut it off with the remote.

Ive been doing this shit for years.

She keeps adding more bible calendars to ward it off.

Taking this one to the grave, Cathy, you cunt.
