Flash Screaming Maze Prank

For a good snicker, send this to your friends, watch them work over and over again to navigate the maze, trying over and over again only to finally near success and...well, you know what happens then, don't you? If you don't, give it a shot yourself (you may want to turn your computer's volume down if you're easily startled) and then try out the lesson to see how it's made.
