Watch the Creepy ‘Slender Man’ Halloween Prank

Because scaring the hell out of people rules, a dude dressed up as internet meme/freaky-looking faceless dude "Slender Man" and hung out in an alley near Chicago's DePaul University. His friend hung out on a nearby roof to film the whole thing and the reaction from most was beyond priceless. A few people even wanted to stop and take a pic with him after the initial shock wore off with one girl opting out after she got a little closer to the creepy sumbitch. Because you never know, it might not be a prank. And that's the beauty of it.
