If you missed WEC 47 live on Versus, go find Anthony Pettus' knockout of Danny Castillo  on YouTube before WEC enters its copyright claims. It's sick.

Here's the text version.

Pettus threw a straight right that Castillo moved to defend. Castillo threw a left hand to counter but missed and left the right side of his body open. Pettus immediately followed with a devastating left leg kick to Castillo's right temple. Castillo was knocked cold instantly and fell to the ground unconscious 2:17 into the first round.

Trust me, go find this clip if you haven't seen it already. Sick. If we don't see it on the WEC Knockouts 2010 DVD, then, well, it must have been one heck of year for MMA under 155 pounds.
