Bruce Lee is one of the most electric action movie stars in history, and his on-screen Kung Fu mastery are still more impressive than special effects heavy modern flicks.
Many people have wondered if he could actually fight, and a grainy video from a 1967 sparing session in Long Beach shows he was more than capable of handling himself. He knocked a guy into a chair with his one inch punch and barely breaks a sweat taking while making quick work of a sparring partner.
Watch this and think about Lee fighting in UFC or MMA. Forget Floyd Mayweather.
