On “Dragon Tales,” the characters in Dragon Land jump into openings in the ground called knucker holes. The name, apparently from dragon mythology, is weird, the look of them weirder. I saw a knucker hole on the show for the first time just now, and there’s no more accurate way to describe it than a sphincter in the ground. It moves as I imagine a sphincter does, and while I’ve never seen the inside of a rectum, and hope never to do so, the tunnel the characters slide down once inside the knucker hole appears as I imagine a rectum does. (I once saw something like this during a dim sum meal and a grown man at the table announced, with a big smile usually seen on an obnoxiously precocious child, that it was a “cow pooper.”)
I think the “Dragon Tales” artists were having a bit of fun, just as I suspect they did when having the dragons dig frantically through their pouches in search of a whistle or other item. Anyway, the next time some fool in a motor vehicle does something selfishly dangerous, I might be tempted to call him a knucker hole — or would if I were the name-calling, road-raging type. Sounds pretty bad even if you didn’t know it looks like a sphincter.
