Every once in a while, an idea comes along that's so perfect, so well done, that you can't help but stand in awe. Shit Senders is that idea. Has your boss made you stay late for the past three nights in a row while he's at home in his mansion with his trophy wife screwing her on, what you're assuming, are dead animal pelts? Does your ex-girlfriend insist on putting photos of her new boyfriend doing body shots off her boobs from their trip to the Cayman Islands on Facebook? Need an anonymous way to get back at them? Send them shit in a box. (For proof of it's effectiveness, read this article about an unlucky MTV executive.)
