The phrase "all show, no go" comes to mind when watching this video. This looks like some sort of underground fight club, and one of the fighters is very excited about fighting. He flips around, getting the crowd pumped up. At one point, he does a hand stand! Well, all the other guy did to show off was throw a punch. One punch.

Upon further investigation, I THINK this is actually a clip from a movie called "Never Back Down" but still entertaining non the less...
