Somebody took Billy Joel's history lesson, "We Didn't Start the Fire", and made an annotated version of the lyrics. Now if only I could find somebody to do the same thing with the theme song from "Cheers".

Seriously though, I'd never heard of George Santayana before reading this annotation, and I'm genuinely amazed that I hadn't. He sounds like a profound and influential figure in American thought. My education blew. via
