Here’s our personal favourite, No: 3 as listed in this site:

Disappearing Desktop

Just head over to an unattended computer, minimize all the windows, and hit the Print Screen key. Paste the captured image into any graphic editing program — even Microsoft Paint will do — then save the file and set it as the desktop background. Then, all you have to do is hide the actual icons on the desktop — put them in a folder somewhere — and your victim will try endlessly to click the nonexistent icons, which are actually just part of the background image. For another variation, leave one program open when you capture the screen and watch as the person tries to click on it, type in it, and close it to no avail.
