Berk provides a fairly comprehensive approach to humor, exploring its sources and the reasons for using it. Humor is not just for finding laughs, he writes, but for having fun and adding stimulation to teaching and learning. The book is light-hearted and offers many examples of wholesome, low-risk jokes, anecdotes, cartoons, 'top-ten lists,' and generous amounts of silliness. The material may be especially helpful to those whom the author describes as being 'humor challenged' or 'jocularly arthritic. - NACADA Journal
