Jimmy Fallon loves all things old school. As the holiday season is just around the corner, Jimmy was reminiscing with his celebrity host Mike Tyson about receiving Mike Tyson’s Punch-Out for the original Nintendo for Christmas when he was a much younger lad. That got Jimmy thinking. Wouldn’t it be awesome to have Mike Tyson play Mike Tyson on the Nintendo? Naturally, he set up the duel for everyone to enjoy on The Tonight Show.
