So I've been on this kick recently where I fall down YouTube MMA rabbit holes, and I stumbled upon this like two and a halfish days ago. This here vid is a tribute to Vale Tudo, which is a precursor to modern mixed martial arts. It has no rules, basically. It is fucking bananas.

The cool thing about this is that there are a few fighters in this video, like Chuck Liddell and Wanderlei Silva, whom we know from them smoking and getting smoked by numerous fighters in the UFC. Here, you see a young Liddell get kicked in the head a couple times, which is always cool, and you see Silva just headbutting the living Christ out of guys. Just imagine how this guy's brain looks.
