A friend of mine told me that when he was in Thailand, he saw a kickboxing match in which there was one guy wearing bells and two blindfolded men. The goal of the blindfolded boxer was to knock out the guy with the bells based on where they hear the sound coming from, while the goal of the guy with the bells is to try to trick the two guys into knocking out one another. Brilliant! And Insane! Both!

I tried like hell to find it, and while I couldn't find this exactly, I did come across a lot of blindfolded fight like this one where the ref gets his ass beat. There is a real nice knockout at 2:20, and there are some annoying American "commentators."

Would you rather be a rodeo clown living in Texas or a ref in blindfolded Muay Thai fights in Thailand? Also, has youtube stopped giving links to embed videos?
