the first 10 seconds scared the fuck out of me already... i'm gonna watch the rest now i just wanted to let you know that i jumped like hell.

EDIT: The first one was the one that scared the shit out of me and the second one was weird as fuck looking... I dunno either could be done with a lot of practice the first could be a pile of leaves and fake body ontop and then someone's head sticking out and when they heard the camera guy get close they screamed and the second could be some guy just running like a weirdo... I dunno I can't say whether I believe it or not.
