Quote from Niles in How to Bury a Millionaire
Martin: All right, now I'm stuck. How do I get down? There's a bookcase blocking my way. Niles: Well, the bookcase is a secret door, Dad. Martin: How do I open it? Niles: Just poke "Mrs. Dalloway" on the bottom. Martin: What? Niles: The yellow book on the lower shelf.
