When you have kids, one of the natural urges as a parent is to teach them how to do various things: one of which is how to play sports.
Unfortunately, not all fathers are up to the job, and should leave the teaching to the professionals, as can be seen in this Bad Dad baseball video clip.
I was pretty shocked when I first watched this, as the kid loses his head out of the blue, and it kind of puts you on edge, and slightly upset.
Obviously, my brain realised quite quickly (bot not quickly enough) that it’s a visual effect, probably a Photoshop job, and the kid is fine… I think.
