Xanthus said to him (Aesop), "Can you tell me why it is that when we defecate we look often at our own droppings?" Aesop: "Because long ago there was a king's son, who, as a result of the looseness of his bowels and his loose way of living, sat there for a long time relieving himself -- for so long that before he knew it he had passed his own wits. Ever since then, when men relieve themselves, they look down for fear that they, too, have passed their wits. But don't you worry about this. There's no danger of you passing your wits, for you don't have any."
