Some of you are not funny and some ofyou are obviously bastards! 😀
Lift receiver, locate button that tells phone it's off hook. Sellotape over said button. Ring phone 🙂
Key swapping on keyboard is a good one, once had to explain to a lass on the phone to the IT dept what we had done, she was going crackers "yes I am sure it's the right password!".
Swap something that he uses for something else that looks like it but that someone else uses. Then they'll both be baffled. Two pranks of for the price of one.
Change mouse to left handed
ctrl>ALT>Down arrow no worky for me.
Fax machines and hole punches??? Give us a go in your time machine mister 😛
Remote log in/conference when they leave their desk. Hide the tab saying "you are in a conference call".
When they come back, edit all their emails as they are typing.
We had one guy flip out and stand up screaming that some tucker was going to get a smack if they didn't stop.
Then IT changed some settings, you get an unhideable banner across the top of your screen these days. Bastards.
Looking at someone and smiling then going back to what you were doing works well if you can get half a dozen or so doing it. Unless it's someone likely to flip. 😳
Some clown caught a seagull and put it in a workmates clothes locker, it was quite a mess.
Subtle one that works if they've said something piss takey in an email.
Edit the address in the stuff that shows previous emails on the bottom of your email so it looks like you've sent it to the boss too, then simply forward to the person you're winding up with a comment saying
"Thanks, I've passed that on to Mike/whoever for his thoughts"
Watch them panic.
Or, like I did, email Mike explaining myself only to be called and asked "what are you on about?"
ctrl>ALT>Down arrow no worky for me.
It's a feature of Intel chipset graphics; it won't work if you've got something else.
I changed a workmate's Windows logoff sound to the Dogtanian and the Three Muskahounds theme tune once. I thought it would just play a bit of the song until the computer shut down but I didn't realise it actually made it play the whole song before shutting down; he couldn't do anything to stop it playing so got funny looks for 2 minutes instead 😀
Prising the n and m keys out on a keyboard and swapping them around is a good one if the person looks at the keyboard to type.
Did this one ages ago to a flatmate, edited the shortcut to his favourite game to a command prompt to shutdown the pc. He thought he had some sort of bug or glitch on the game 🙂
Grab them in the toilet and squirt jif lemon juice down his japs eye !
Do some work?
Someone in our office was away for a couple of weeks on honeymoon. While he was gone we steadily, a little bit each day, covered everything on his desk in tin foil. To the level that we dismantled his fan, wrapped the blades, reassembled and then wrapped the whole. Similarly, someone working late found a box of raisins in his desk, wrapped them all individually, then the box. Same with the half full glass of water. My contribution was to carefully wrap all the keys on the keyboard so you could still read the letters- he kept using that for quite a while
Shit on their desk
Didn't see this one done myself but liked the sound of it.
New toaster in the office.
Turn it round so the buttons face the wall and can't be seen.
Post-it note on the visible side without buttons "New Toaster. Voice-activated."
Sit back and listen.
Ok as this is still going I have another. A colleague was having a bruising time on one project with a project manager who was a complete BAs£ard. I left a post it on his desk saying the 'tony' had called and seemed pretty upset about something could he call him back. You could see the stress on his face as he dialled. It was one of those mr angry lines where the replies are perfectly timed. Anyway he went through the whole call spluttering as 'Tony' raged on the other end. Eventually 'Tony' hangs up. My colleague ashern faced said 'I think I had better ring him back it's pretty serious'. So he rang back and went through the same intro until it dawned on him it was the same. At which point he shouted quite a few rude words at us as we were wetting ourselves laughing.
In the regional paper today there was a piece about some bloke who put Viagra in his boss's drink as a prank; the court took a very dim view of it!
I hope they're not too hard on him. LOOOOOLOLOL.
...put Viagra in his boss's drink as a prank...
Did he get a stiff neck?
A colleague once bought some remote control power socket things in Lidls. We plugged this blokes computer monitor in to one, sat across the office and every time he moved the mouse, click... monitor goes off. Eventually he's crawling about under the desk to see which cable is faulty.. finds the remote socket. How we laughed.
