Go The F**k To Sleep by Adam Mansbach

Written by an exhausted and fed-up parent, this is a hilarious children's book for adults.  Mansbach has struck gold by publishing what every parent has thought at some point about getting their child to sleep.  You don't even have to be a parent to be entertained by this book, although I think it's a great gift for first time parents.  Extra funny is this YouTube clip of Samuel L. Jackson reading the book.  As a warning though, if you don't like swearing, you probably won't like this book.
