My Funny Picture

I need some funny computer pranks...?

Does anyone know of any that are really quick, easy to do and easy to fix, and funny? And obviously, no harm done to the computer? For example, last week my friend changed my desktop and made it rotate 90 degrees! I took me forever to figure out how to change it back.
