In mixed martial arts, you have one job to do: win the fight by points or by knockout. When you're planning a knockout, it should be to your opponent.

You might be wondering how it's possible to knock yourself out, but these guys prove that impossible is nothing and they can turn the lights out on themselves. Here we have some unbelievable MMA self knockouts for your viewing pleasure.
