This book is a masterful mixture of hilarious pranks, fun stories, and a grand tour of the life of one of our greatest Physicists.  I greatly enjoyed listening to it.<br><br>Feynman's way of seeing the world made for a very fun narrative, and oh the pranks and accomplishments he pulled off... Take the fact that there was a guy sneaking around the Manhattan Project breaking into safes, but he was on our side and doing it to prove they were insecure (and because it was fun).  That was Feynman.  He took a vacation by studying another field of science (biology), instead of hitting the beach.  He was a womanizer, a professor, a prankster, and a physicist.  And yet he fit all these together seamlessly into a single, coherent, brilliant person.  The contrasts make him all the more likable.<br><br>There are some dark or sobering moments in the book as well, including: his reactions to seeing the nuclear bomb's power and imagining what might come next, his scary brush with the threat of alcoholism, trying to fix the problems with Brazil's educational system at the time, and his frustrations with people believing in bad (poorly done) and outright fake science.  These moments help balance the story's hilarity, but such moments are still rare.  Overall the book is very upbeat and funny.
