Query: You gotta be kidding!

It's cute, it's quaint, it's memorable. Yes, the book will become a "meme" for everyone. But I cannot believe people don't already know this. On the other hand, maybe people have gotten so caught up in their lives they've forgotten the basics. Don't buy it, though--borrow it or check it out of the library. Take the 30 mins it requires to read it, and then you too can say you know what people are talking about. Then, get on with your life.
