However deranged Trevor might be, he's just a fictional character. But if he wasn't? What if he was a real person that roamed our streets? It would be kind of amazing. And by amazing I mean slightly horrifying.
Check out these series of pranks by Nathan Barnatt, where he pretends to be a Trevor. Trevor, apparently, has a 'dead body'—the guy is most likely not actually dead, but it is a real person Trevor is carrying around. People react to that, and it's pretty hilarious.
