My favorite don't mess with a martial artest videos.
This guy is a true martial artist, he kept his cool, one hit and then walked away. I've been in martial arts for 20 years, and so few people learn this, the most important part of martial arts. I always asked my new students one question. Why are you taking martial arts? the answer was always the same. To learn to fight. And my reply was always the same. Wrong, you learn martial arts to learn how not to fight. This is what makes a true black belt.
