These guys decided to set up a little Halloween themed prank in a public park late one night and we couldn't applaud them more for it! They left a bike propped up against a caution sign as though it had been left behind with no one to watch it. Really though, it's tied to the near by tree with a chain. When would be thieves would try to get on the bike and make off with it, they're immediately terrified to see a chainsaw wielding maniac chase after them! Of course they try to take to the bike to flee but when the chain catches and they're tossed, well, as you can see their adrenaline starts working overtime!
