Query: not funny.

I'm not really a kid, I just didn't feel like signing in.I expected a lot from this book and was completely disappointed. It's not funny! You know that friend of yours who drags the joke out way too long? that friend is this book. I laughed a couple of times in the beginning and then I realized that that was about as good as it was going to get. And past the unfunny jokes, I felt like I was getting beaten over the head with the war-is-crazy, beaurocracy-is-endless message. He could have accomplished the same thing in 300 less pages. I can't believe I actually wasted my time reading this.
