First, there was the martial arts movie classic Bloodsport, which featured a "monkey fighter" who would bounce around the ring using both his hands and feet on the mat. Then Jon "Bones" Jones did a variation on that move where he tried to set up a single leg takedown against Rampage Jackson in their title fight. Jones didn't get his takedown, but neither did he get cracked in this face for his efforts, unlike the poor guy in this video.
Under Pride rules, you would not see monkey style tactics used, because of the dangers of getting kicked in the head. But under the unified rules, you cannot kick the head of a downed opponent (i.e. where the fighter has a hand or knee on the ground). So when this guy got cracked, his opponent was DQ'd. On the one hand, it's always nice to get a win, but on the other hand, this is not the way to do it.
Above is the video of the DQ. After the jump you can check out the Bloodsport original, as well as Jones doing it against Rampage.
