It's in muay thai. But watch what happens...I've never seen something like this.
Not even during the Rahman vs Maskaev fight.
Or even in the coleman vs shogun post fight incident in Pride fc.

damn that was crazy. i didn't get a chance to hear what the guy said, but that was insane. dude got hit with a cheap shot knee tho.

it's like Riley from the Boondocks said, "throw a chair and people are gonna start fighting." i guess it's true.
