Penn will make you laugh. Even when you are supposed to cry. If you ever listened to him, this book will be way more fun. It's like hear him talking. Its like an audio book in your mind. The atheist topic is a huge excuse for a boat load of great stories, some of them of the atheist topic.
It helps on your reading time if you already like Penn. You will roll over bits about early stages on his career. You will also learn about odd encounters, like the one he had with Christopher Hitchens, not letting the guyd get into his house with a botle of booze in his hands.
Every Day is an Atheist Holiday is a pack of tales. All funny, some humbling and some incredible. Great read!
