This guy was trying to be like Kramer, hitting golf balls into the ocean. The problem here was twofold: This guy didn't have much of a swing and there was a bulkhead just high enough to catch a piece of his drive.
When he makes contact, it sounds pretty decent, but the ball launches low. Instead of heading into the body of water yonder, the ball ricochets of the bulkhead and then hits the man in the side.
And that's why you don't facetiously yell "Fore!" into the camera before you take a golf swing.
