In 1937, then heavyweight champion of the world, James (Jim) ‘Cinderella Man’ Braddock went up against the Brown Bomber, Joe Louis, for the title. 

The title as you’ll see below says it all in the proverbial nutshell. If you have time to watch the entire fight, please do – it can be found at the same link. It’s incredible to see how the art of boxing has changed over the years, from the likes of Braddock and Louis to the man who floated like a butterfly, Muhammad Ali. The eighth round, however, is the highlight. The video will begin around the 18:45 mark – you can see the slow motion replay around the 19:00 mark!
