I wouldn't feel bad. It is, most likely, a fake intended to bamboozle the viewer. The first part with the woman subject is real and legitimate. The second part with the doofus is made up. Clearly it was taped at different locations with different setups. You can see that from (a) balls of different color (b) the structure of the wall behind the subjects' heads: sturdy cinder blocks behind the woman, flimsy plasterboard behind the doofus.
Mechanical energy conservation requires that, after a complete swing, the ball will return to the same point with the same speed. This is obvious in the first part of the video. In the second part, the ball appears to move faster when it returns. Indeed, I counted frames and found that it takes about 2½ frames worth of time for the ball to disappear from view on its way out whilst it crosses the same distance and smashes the doofus's nose from one frame to the next. Either mechanical energy is not conserved or an external force acted on the ball while it out of sight to add extra Joules to its mechanical energy.
Finally, the pièce de résistance is the shape of the hole in the plasterboard that we are expected to believe was created by the doofus's head busting through the wall. OMG it is soooo consistent with
Cartoon Law of Physics III,
Any body passing through solid matter will leave a perforation conforming to its perimeter. Also called the silhouette of passage, this phenomenon is the specialty of victims of directed-pressure explosions and of reckless cowards who are so eager to escape that they exit directly through the wall of a house, leaving a cookie-cutout-perfect hole. The threat of skunks or matrimony often catalyzes this reaction.
I rest my case, LOL.
