Who ever though of this prank is a genius in my mind. As we see in this YouTube video some guy dressed up as Jason from the 'Friday the 13th' movies hangs out in random places and then as people pass by he comes out of the shadows and starts chasing after them with an actual chainsaw. Now, that being said, while this is the perfect prank for Friday the 13th, It is a very dangerous prank, that and you may find yourself in jail if you try it. So, it probably shouldn't be recreated in any way. And besides, this is Flint, pulling a chainsaw on someone might result in your own death. Ever heard the one about taking a knife to a gun fight? You've been warned. Now, watch the video.
