FUNNY PRANKS | Harry Potter Dementor Prank  
What would you do if a dementor (the hooded un-dead creatures from "Harry Potter") walked up to someone sitting near you, touched them on the head, uttered a few words of magic, and seemingly killed it's target? Well, if you were a normal person you'd probably have a laugh... but others, like the people in this video, might get a little freaked. Gotta love that guy at about 2 minutes in!
