Someone once tried to tell Chuck Norris that roundhouse kicks aren't the best way to kick someone. This has been recorded by historians as the worst mistake anyone has ever made.
Upon hearing that his good friend, Lance Armstrong, lost his testicles to cancer, Chuck Norris donated one of his to Lance. With just one of Chuck's nuts, Lance was able to win the Tour De France seven times. By the way, Chuck still has two testicles; either he was able to produce a new one simply by flexing, or he had three to begin with. No one knows for sure.
Before Chuck Norris was born, the martial arts weapons with two pieces of wood connected by a chain were called NunBarrys. No one ever did find out what happened to Barry.
