WORLD’S MOST ANNOYING HOME PAGE: Imagine a home page that pops up hundreds of funny messages, one after another, with no way to stop them until the stream of messages is finished! It’s perfectly silly, and perfectly harmless. To use it properly, just get on the computer of someone you’d like to prank and set their browser to load the World’s Most Annoying Home Page whenever it starts up. Hours of fun—each time they load it!

WORLD’S LONGEST START-UP SOUND: Most computers have a quick sound that plays when the computer starts up, but how about changing that to a four-minute epic musical piece? This one is designed to sound like the Windows start-up sound, but is much, much longer. Warning: This may drive them insane after one use!

PRANK WALLPAPER: One of the easiest and funniest pranks you can pull on someone’s computer is to replace their desktop wallpaper with a silly graphic. When they come back to their desk, they’ll think their computer has gone wackadoo. We have several free prank wallpapers for your amusement, including one that makes it look like their screen has cracked and another that makes it look like someone has put over one hundred icons on their desktop (perfect for neat freaks who like to keep their computer organized).

TURKEY MOUSE: Here’s a simple prank you can do on a relative’s computer that will get everyone in the holiday spirit (whether or not it’s the holiday season). Every time they click a menu, it will make the sound of a gobbling turkey. Best of all, it’s easy to put on their computer and easy to take off. Not for the easily annoyed or those with an extreme fear of turkeys.
