Some people just can't take a joke, it's not really for parents to read to their kids! For anyone who thinks that this is a serious book that actually suggests that parents tell their children to go the f*ck to sleep, then you're an idiot. It's like a joke book, if a stupid manager of a bookshop places it with the other children's book and then is appaulled when a child picks it up, then that's their fault.
It's a funny book, it's the kind of thing new parents might get as a present from a friend as a joke. I actually listened to the audio of it by Samuel L Jackson and it was hilarious, I don't even care that much about it, I just though the rating could do with some balancing.
