Many people thought about it, many people speculated how it would be, not so many people believe it would not work, but Brett Cohen, an illustrious not famous guy, did it.
He got together some photographs, some security man, a few people to start some noise, an improvised camera crew and walked in Times Square, in New York, pretending to be some kind of celebrity. Take a look.
The most fun thing to me are the people telling they knew him from somewhere by simply repeating what someone said first. Thinking a little further, I also think it is funny how excited some people get to take a picture with him. I mean, really, I don't know if it is some problem I have in my head because I don't sleep enough, or is it because I listen too much podcasts, or if is just bad luck, but I just can't understand this idea of "Oh, you are famous, let me take a picture with you!". I really can't.
Perhaps it is something from people who doesn't know much about Photoshop, right?
