Video: 62-year-old scores brutal spinning back-fist knockout in MMA debut

Take note Ken Shamrock, this is how you deal with young whippersnappers like Kimbo Slice.

This great clip will make CM Punk hopeful that he can turn some heads in his UFC debut. This unnamed 62-year-old (admittedly, a couple of years older than Mr Punk) decided that he would try his hand at the purest form of unarmed combat. His opponent had the temerity to underestimate the aged after beating him around the ring and out-grappling him. However, as GSP found out against Matt "I lost my battle with complex carbohydrates" Serra, all it takes is one punch to change the course of the fight. In this case, that punch was a spinning-back fist and although the technique was suspect, you can't argue with the outcome. The vicious haymaker dropped the cocky younger fighter and left him visibly dazed. The referee called the fight to a halt and awarded the 62-year-old debutante the KO victory. https://www.youtube.com/watch?v=q0vNUx1nmw8 Hat-tip to Reddit
