So a punch line I thought up in high school finally got a set up today. Forty years may seem like a long time, but in the grand history of civilization it’s just another slowly unwinding bit. Centuries might pass between laughs. Concepts await understanding. Ironies not yet ironic. Knock knock said Aristophanes. No one laughed. Take my life, please, said Socrates. And they did. How an elephant got in my pajamas I’ll never know, said Jesus. But it was a rough crowd, and they crucified him.
