A list of pranks to try at the office.
Copier Needs Service
Type in giant bold letter "Copier Needs Service Soon" and make a few copies of the page. Then place the papers back inside the copier paper tray.
Paper Clip Daisy Chain
Take out all of your co-worker's paper clips and link them together, then put them back in the box.
Water Cooler Cups
If your office has a water cooler with paper cups on the side, then this should be an easy prank. All you have to do is puncture a tiny hole with a thin sewing needle near the top of the cups. When your co-workers go to get a drink of water. they won't notice the hole until they drink it and notice the dribbling of water down their shirt.
Stuck Desk Drawer
Go underneath and behind desk drawer to tape it up so it cannot open all the way. This will frustrate your victim who needs to go in the drawer just to grab a pen or a notebook.
Switch M and N keys
While your co-worker in the next cubicle is away, switch the M and N keys on his keyboard.
Pimp Your Chair
Install some buttons and lights in the arms of your chair to make it look flashy.
If you know someone that uses a phone with a hook that presses down when the handset is in the craddle, then tape that part down. When the person tries to answer a call it will just keep on ringing and ringing.
Upside Down Cup On Desk
Fill a cup with water about half way. Then place an index card over the cup. Then turn the cup upside down on your co-worker's desk. Finally, carefully slide the index card out from underneath the cup. Whenever your co-worker decides to pick the cup up, he will be drenched in water.
Stuck Chair Wheels
Use some black tape to tape up the bottom wheels of your victim's desk chair. This will make it difficult to move the chair.
Make a few copies of paperclips then put those copies back inside the paper tray. Whoever uses the copier next will get their copies with those paperclips on them and will look all over trying to hunt them down.
Whenever someone in the office asks you to do something, ask them to sign a waiver first.
Put the trash bin on your desk and label it with "IN".
Telephone Cord Switch
Switch the telephone cords for 2 co-workers that sit next to each other.
Desk Drawer Switch
Before your co-worker arrives at the office remove his desk drawers and switch them around. He will definitely scratch his head over this one. Hint: In case you cannot remove the drawers, just remove the items and swap them
Take all of your co-wrokers pens and replace them with your pens that your glued caps on to the night before. He will not be able to take the caps off to use the pens.
Computer Wallpaper Prank
If someone leaves their computer unattended copy the whole screen (prt sc button on keyboard) paste it in Paint and save. Set it as the victims new wallpaper and delete all the normal icons on the desktop (if you print screen the whole thing, icons will remain on the picture). Your victim will go crazy trying to click on the icons and start a new program but nothing will happen.
