Never underestimate anyone, I agree Tom.
On a side note Chuck Norris started off in Tang Soo Do which is not exactly like modern sporting Tae Kwon Do well at the time Chuck started learning it in Korea it was not, these days I am not so sure. Also Chuck changed his style to universal way which added BJJ and TKD with Thai Boxing and Shotokan to the Tang Soo Do base system. Wonder why he changed it
I also herd rumors that he may have taken some lessons from Bruce Lee but I do not know how much of that is true... maybe you know?
