Big fan of David Blaine, just found this clip on youtube, you would'nt want to be caught down a dark alley with this man, the first punch must have hurt, but second one gets him good!!!
I find it hard to believe that any man could take that and not drop to his knees (at the very least) if it was staged then Kimbo would have to be in on it right? There is a lot of Dynamo's tricks revealed and it looks like people such as Rio Ferdinand are in on it, so its not unheard of.
