How many tickets to get your brain cells back?
This is practically a PSA for being an involved father: you never know when you are going to be able to point out to your kid how other children are stupid and wrong and that's just life. Judging from the video, this dad is coaching the kid throwing the balls and some wandering idiot-child just submits himself for pain. This is an important life lesson for all of us: sometimes you feel like you're throwing 100s in life and some moron puts his face down in your path and gets hurt by accident. You may want to feel bad, but you weren't the one who was curious what a rapidly-approaching projectile would look like head-on.
