Bruce Lee vs Chuck Norris is considered to be one of the greatest matches of all time. A lotta people think that it was fake because it was in a movie. But from what I heard, their encounter was not scripted. They knew that they were gonna to be going toe to toe but the had no idea how it was gonna play out.
As far as Chuck Norris coming back to life, I don't know how to explain that one. Except, maybe he never even really died.. Maybe he was faking it cause he saw my video about playing dead when you're in a headlock.. That's pretty firme now that I think of it.
