Lyoto Machida vs. Rashad Evans
Artist: UFC 98
"Sugar" Rashad's Light Heavyweight reign lasted all of nine minutes (and let's be real, much of that was spent dancing around the ring with Machida). And then at the 19:50 mark of this clip comes the onslaught of Machida Karate, and Evans is out before he hits the canvas. With the short term memory loss associated with blows to the head, Evans probably doesn't even remember that he ever was the champ.
