The source of the word "humorist" is one who regards human beings in terms of their humors, you know, whether they're sanguine or full of yellow bile, or whatever the four classical humors are. You stand back from people and regard them as types. And one finds, especially by the time one reaches one's fifties, that there are a limited number of types of people in the world, and you went to high school with every single one of them. You can visit the Eskimos, you can visit the Bushmen in the Kalahari, you can go to Israel, you can go to Egypt, but everybody you meet is going to be somebody you went to high school with.
