Welcome to the worst news day on the Internet. While every other site is busy posting fake news, the humorless bunch at Tested .com will be gluing people's mice to their desks and filling people's offices with styrofoam peanuts. Oh, and we're going to show you how to prank the hell out of your friends too.
There are veritable cornucopia of killer pranks you can pull on your coworkers and friends. Everyone's heard of the old standbys, like plugging a spare wireless mouse in to someone's computer, then making their cursor go crazy throughout the day (for bonus points, control the mouse with your feet, so they won't catch your hand movements), the old tape over the mouse sensor trick, and the always classic desktop wallpaper instead of desktop--although we do have a killer variant of that one that will actually melt your brain.
Oh, and don't forget to lock your workstation (that's Win+L on Windows, but you can use LockTight to do the same thing on the OS X) any time you get up tomorrow, or risk being the fool, rather than the fool-er. Oh, you didn't prepare for your prankery before you came to work? Fear not, six outta seven pranks require no preparation.
