Query: MUST READ

This book is amazing... I just starting reading it and can't put it down.. The book is thought provoking and funny at the same time.. Read this book, and pass it on to your friends... The US needs more people that are educated on what our tax dollars support.. I also highly reccomend his latest movie "Bowling for Columbine"... A must see.
