The gorillas at the San Diego Zoo (the one with no bars, no shatter-resistant windows - just moats) circa 1968-1970 used to sit up on the top of the rocks. When someone became a bit too impolite (in gorilla terms) the gorillas would use the height to their advantage.
Squat.
Fill hand.
Profit.
They were fairly accurate, too. As in probably within a 5* arc from somewhere between 45 & 50 feet. So if what the gorilla did was not enough to correct your behavior, the folks around you were sure to "help out".
I wonder if that behavior was taught to succeeding generations.
stay safe.
