How? He's kind of, Chuck Norris. It isn't that easy. You have to stand up to him in combat, which most people wouldn't risk. That's why he only has 2 friends, himself, and another person I probably shouldn't mention.
Chuck Norris feels pity for him, and gives him a free shot. Bruce Lee punches Chuck Norris's chest, and Bruce fractures his hand, arm, shoulder and spine.
