Punching bags have it rough. They are punched, kicked and elbowed all day long, and seldom do they get to hit back, but when they do, it’s priceless. This guy (who has awful punching form) learns the hard way that a non-stationary punching bag will rebound at some point and hit you with the same force that you have exerted. The best part? The guy’s hat flying off when he’s smacked in the face.
