Query: Forget about buying this book.

This book was the worst investment of my life. Borowitz is not at all funny. It didn't even make me smile. This book is a waste of ink and paper and it's contents at the very least are downright stupid. A ten year old child has better humor. Save your money and read the daily comics, you'll be better off. I wanted to rate this book with no stars, but this form requires that field to be rated.
