Randy Couture vs. Gabriel Gonzaga
Artist: UFC 74
Couture showed his O.G. MMA credentials when he bludgeoned Gonzaga bloody in this heavyweight championship bout at the ripe old age of 44 (beginning around the 14:40 mark of this clip). The three-time champ beat his much younger opponent like it was his little brother—you know, if that family encouraged violent sadism among siblings.
