Well, let me tell you something, funny boy. Y'know that little stamp, the one that says "New York Public Library"? Well that may not mean anything to you, but that means a lot to me. One whole hell of a lot.
Sure, go ahead, laugh if you want to. I've seen your type before: Flashy, making the scene, flaunting convention. Yeah, I know what you're thinking. What's this guy making such a big stink about old library books? Well, let me give you a hint, junior.

Sure, we're too old to change the world, but what about that kid, sitting down, opening a book, right now, in a branch at the local library and finding drawings of pee-pees and wee-wees on the Cat in the Hat and the Five Chinese Brothers? Doesn't HE deserve better?
