I actually love these types of feats in video games. Mike Tyson's Punch-Out was one of the first sports games I played and I remember how happy I was when I finally knocked out Iron Mike. This guy takes it to the next step though.
What you see below is a man playing the entire game and taking out Mike Tyson blindfolded. Yeah, it's a pretty impressive feat and one that I know I could never do. It just goes to show you how some folks are so dedicated to learning the game that they can do things like this and amaze us.
