I don’t know, it’s hard to make up a very crazy one. Like witches or something like that. You tell about what people used to believe in witches. And of course nobody believes in witches now. And you say, how could they believe in witches? Then you turn around and you say, let’s see, what witches do we believe in? What ceremonies do we do? Every morning we brush our teeth. What is the evidence that the brushing of teeth does the centigrade and cabbage. You start wondering. Are we all, imagine as the earth turns on the orbit, there’s an edge between light and dark. And along that edge, all the people along that edge were doing the same ritual for no good reason. Just like in the Middle Ages, they had other rituals. And you kind of picture this perpetual line of toothbrushes going around the earth. It’s to take the world from another point of view. Now it may well be that brushing teeth is a very good thing because it gets rid of cavities and you can find out whether it does or it doesn’t by trying to find out. ...
