Anyone know any good computer pranks.

Doing this while someone is flashing their bios makes their computer 10-7 for a long time!

I already did the .bmp wall paper thing but you guys have given me lots of ideas... thanks.

I'm also going to go to staples tomorrow and change some of the screens to have a wallpaper of the desktop. Haha knowing that most of the people at staples are dumb (no insult to any technically savy staples employees here) they will probably have no idea how to fix it. Lol if they return them to their manufacture because they won't unfreeze.
