Conspiracy theorists are buzzing about this video, where a guy describes the weird encounter his colleagues had with two "men in black" who were asking strange questions about him. He even got some footage of them from the hotel's security camera. Apparently these two absolutely identical men, in identical black suits, came into the hotel where he works and started asking everybody questions about him. Then, with no explanation, they simply left. Even if this is totally made up and/or viral marketing for the new Men in Black flick (or the new Observers-centric Fringe), it makes for a great story!
