I originally went into this book thinking it was a self-help book, but very quickly realized I was mistaken. After reading half of it and then starting over and reading the entire thing several months later, I can honestly say that knowing that is a humor book doesn't make it any better.
In the book's defense, it presents a kind of lowest-common-denominator, often mean-spirited humor that I rarely find funny in any context, so the fact that I don't have anything more positive to say about this book than that it's short would not have been a surprise if I had known anything about the book other than the title before I began reading.
In short, I can't recommend this book to anyone, but if you happen to have a sense of humor that I'm struggling to find non-pejoritive adjectives to describe, I might encourage you to ignore what I've said.
Sometimes when you feel a need to read ALL the books people give you, you end up with flops like this. I have to wonder if the book was purchased mostly for the penguin on the cover.
