We have a really irritating guy in the office and as its April Fools day on Wednesday was looking to play a prank on him but we can't think of anything.

Thought some of you on here may have some ideas please..

Put some dog poo in a bag and tape it to the underside of his desk.

Take the wheels of his office chair so when he goes to push himself back his chair will fall over with him in it .

the old fake parking ticket always works for me, photo copy some black writing on a yellow background, plastic bag, car wind screen, hey presto!

ctrl Alt & Down if hes got xp

Best one if you have time. 'Print screen' his desktop and put it as the background, then hide the tab bar at bottom of screen and put all the icons in the recycle bin (can get them later). Or alternatively you might be able to disable them by right clicking on background. will try to click on the icons but wont be able to as he is clicking on the background.

Or/as well

Swap his Keyboard from Qwerty to the 'Dvorak' layout

Glue his pens to the lids, or just paint nail varnish onto the tips so they don't work.

Can also change the mouse so its left handed (left clicks are now done with right click and so on). Or if its one with a infared light, tape over the bottom.

Leave a message on his that says that a “Mr. Lyon” called (or Mr. Behr), and wants to be called back. Then list the phone number of the local zoo. #

Few off top of head

Oh as well, as i've started using windows for a bit as well as mac im back to seeing the 'blue screen of death', try it as a screensaver

Can ironically download it from Microsofts website.

how do you undo that?

ctrl alt and up.

Obviously!
