He has a Belt in Rex-Kwon-Do.
Also as far as MMA KO's go this one is the most impressive Ive seen. I cant imagine getting caught with it though. But the dude that lands it acts like he does it all the time.
And this KO is also very impressive. I mean he got caught with a caporiera (sp?) kick so the level once again aint that high. But the most impressive part of the video is at 22 seconds when his boy flips over the top roperto give the guy some props. Then his other boy at 26 seconds tries to go between the ropes and falls right on his face.
