</div class=img_thumbleft>In this week's cover story, The Ballad of the Muscle Shark, Paul Demko profiles Sean Sherk, the Ultimate Fighting Champion. An excerpt: "It gets in your head, just knowing that blood's all over you," [Kenny] Florian says. "It's kind of a disgusting feeling. That blood becomes like a red oil. As far as trying to execute certain techniques, it becomes damn near impossible. For me, it was worse, because that blood was dripping directly into my eyes, my ears, my mouth. I couldn't see out there. I'm gargling on Sherk's blood." What's your take on ultimate fighting?
