This book's author, James E. Larson, believes puns are an example of intelligent humor. At first, the reader is trying to figure out the juxtaposition of two different words that may sound identical but have two different meanings of the words to obtain their exact definitions. Either way, you are learning something which is a good thing. The author hopes you enjoy this book and it brings you a smile at least. In today's world, that is sometimes all we need during the day.
