A third base coach giving signs.
Run the hand along the bill of the cap, touch the nose, swipe across the letters right to left, swipe down the right arm, tug on an ear, swipe across the letters left to right, go to the belt, tug on the other ear, swipe down the left arm, clap twice and spit.
You have to be fucking kidding me.
Gotta keep the opposition from stealing signs, but that is serious overkill. I believe they still do it that way because it has become ingrained in the sport - it is a thing - and because they think it looks cool, and they feel cool doing it.
And the batter has to stand there for two and a half minutes squinting down at the coach to pick up the one gesture or combination that means something.
I think it is fucking hilarious.
