When you're playing a prank on your friend and video taping it, you're going for the best reaction possible. When you get a man to scream like a girl, that's even better. That's what happened with this prank where a guy set up a fake mouse in order to scare his friend, and I don't know if I've ever seen anyone move as fast as this guy did. Really, it's just a fake mouse... what are you getting so excited for?

What kind of pranks do you play on your friends?
