Batman: Robin, I've been studying the Bible, and I've come to Ecclesiastes.

Robin: It's a book of wisdom, right, Batman?

Batman: Yes, indeed! Ecclesiastes 1 starts off with the words "Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity."

Catwoman: What does that mean, Batman?

Batman: It's the Preacher's conclusion that all of life's pursuits are futile and nothing new can be gained from them. He points out that generations come and go, and no matter what is done, it all eventually fades away.
