office prank...would this really work..
Step 1
When your mark wanders from his desk, go to his computer and click his keyboard's Print Screen button—this saves an exact replica of his desktop to the clipboard. Your goal is to turn this image into the computer's wallpaper, so open Microsoft Paint, paste in the image and hit Save. Name the file "jerkweed" and store it somewhere on his system.
Step 2
Drag all files currently on the desktop (even the My Computer icon) into a new folder. Hide it somewhere on his PC. The desktop should look like a blank slate at this point.
Step 3
Open the Jerkweed file. Right click it and choose Set As Desktop Background. The snapshot of his desktop is now the wallpaper. All of his files will still appear to be on-screen, even though they're hidden elsewhere. Sit back as your victim frantically clicks around and wonders why his programs and files are "frozen." Suggest he shutdown, re-boot, and run antivirus software. When all methods of recovery fail, hand the nancy a lotiony Kleenex tissue. :p
