We’ve seen a few pranks in our time, but none were as intense as this chainsaw massacre prank. Just imagine it. You’re walking to your car or to the elevator and all of a sudden you see a man completely slaughter another person in front of you. Then once the man notices you, he starts chasing after you with his chainsaw. We can’t think of a single person that wouldn’t be scared to death in this situation. We’re just happy we weren’t involved because we don’t think we’d be able to sleep for at least a month.
