"Whenever I'm giving talks, I always ask people to think of the most obscure questions because I enjoy those the most. I always get the same questions: Why does Pickwick say "plock" and will there be a movie? I like the really obscure questions because there's so much in the books. There are tons and tons of references and I like when people get the little ones and ask me about them. It's good for the audience [and also] they realize there's more there."
