These are some great computer pranks that I found on youtube. You can do this office prank in a couple minutes. The first prank will create a shortcut icon that looks like Internet explorer but in all actuality it will create an icon that when clicked will shut down your computer. It has a custom message, a timer and no way of clicking out of it. Great HUH. The next prank in the video is the classic desktop print screen prank. Try them out on your friends they are instant classics.
