From the Boss, PLEASE SEE ME: Get to work a few minutes early (before co-workers get settled at their desks). Write PLEASE SEE ME in bold, capital letters on some sticky notes / Post-Its, and sign with the name of the most senior person in your office (who might have a reason to be upset with one of your co-workers). Stick them on a few co-workers' computer screens.
Delete desktop: Take a screenshot of the Victim's desktop (showing all the icons, shortcuts etc.). Set it as the desktop background, then proceed to delete each and every one of the items on his/her desktop (they can retrieve them later from the Recycle Bin). When the Person tries to click one of the items on their desktop, nothing will happen of course (because it's a background image lol). They might think their computer is hung up, and might reboot it a couple times, or call the I.T. department, who knows, just stay low when the trick is found out :)
Out of paper : this one is perfect for someone who's just clueless about technology. Tell the person that another department (or location) is out of copier paper and that you need him/her to fax a few blank pages to them, just enough to hold them until their paper shipment arrives. This would be perfect if faxing stuff is already a part of the person's daily routine/tasks, so it won't seem like a particularly unusual request.
Fake email notice about a burst of concentrated air: If you manage an office mailing list or work in the I.T. department (recognized name), you might be able to pull this one off. Send out an email notice to all staff, announcing that the phone company needs to clean the built-up dust out of the phone lines and that everyone should unplug their phones because a burst of concentrated air will be sent through the phone lines at a certain time, and that if the phone is not unplugged, the cubicle will fill with dust.
You won lots of money: pretend you just won a ton load of money while playing at an online casino, then flip the bird at all your co-workers and supervisor while telling them you're 'glad I can finally ditch this sorry joint'.
Foil Everything: This office prank should be performed in
small offices or in an ofice where a lot of people are willing to
gang up against one particular co-worker. Here's how
it goes - buy several restaurant-size rolls of aluminum foil. Wait
'til the "victim" leaves for the day on March 31 then
go into their cubicle or office and wrap EVERYTHING in foil: desk,
chair, computer, books, pencils, etc. If enough people chip in and
help, it won't take too long. Be sure to take lots of pictures!
Drawer Madness: Remove the desk drawers in the persons
desk and switch them around. If you cant remove the drawers,
just take out the stuff and swap it around, move it all over the
place. They'll look for stuff where they know it should be and can't
find it there.
Free, 'Fresh' Donuts: Buy a box of donuts a few days before
April 1st. Keep them at home in the refrigerator with the top open
until they are very dried out. Bring them to the office on April
Fool's Day and put them by the coffee maker so everyone will help
themselves to the free 'fresh' donuts.
Cheese sandwiches: Make a dozen or so cheese sandwiches for
your co-workers. Keep the wrapper on the cheese slice. When they
bite into it, they'll get a nice surprise.
Swap the Boss' newspapers: You'd have had to start planning for this from the previous year, and it'll work well if he/she gets a particular newspaper on their desk every day. Save the newspaper from April 1 this year (keep it sealed in a Ziploc bag or something so that it's well preserved and doesn't look old). On April 1 next year, swap the new with the old newspaper. Let's see if they even notice; hopefully they have a sense of humor :)
Vaccum packed cubicle: How about sealing off your co-worker's cubicle with plastic wrap, then fill the cubicle right up with packing material and filler. Demonstrated below :)
