I was just watching Pride FC and some dude got kneed in the crotch so hard it shattered his cup. He couldnt walk and was all woozy. He had to be taken out on a stretcher. Sucks for him. On the last Pride Mirko Cro Cop tried to kick a guy in the head, his ankle bone grazed the top of the guys skull and blood went EVERYWHERE. It was crazy. Very fun to watch.
If you don't watch MMA competitions I suggest you watch Pride. It is huge. Its based in Japan and it is much much bigger in Japan than here. I couldn't believe how big the venue and the crowd was the first time I saw it. www.pridefc.com
