People who don't do muay thai fail to understand how useful it is to kick an opponents arms. If your power arm is a purple and red pulped mess, you tend to avoid using it :)

In the second video, count how many kicks Yodsaenklai delivers to the power arm of poor Bruce McFie. Midway through the fight, Bruce says to his cornerman, "He's smashing my arm" ... I thought that was a little bit of an understatement ;)
