This here is my favorite book. I suppose The Road meant more to me, but when I'm taking my entrance test for heaven, and they ask me what my favorite book was and why, I'll say this one. And it'll be because of the amazing world Heinlein created, and the amazing characters he had populate it, and the ideas, which aren't always new -- in fact, certain of them are awfully old, and crusty from disuse -- those characters have, and the story, oh!, the amazing story of the liberation of the moon. I have a tattoo with a brass cannon over a field or stars with a red bar sinister and the acronym TANSTAAFL on my left arm. This is my favorite book.
