“Analyzing humor is like dissecting a frog. Few people are interested and the frog dies of it.” E. B. White's observation should not be mistaken for a discouraging comment. Rather, it's a good reminder of what happens when you try to scrutinize humor. Humor is indefinable. What makes one person laugh may confuse another, and if someone doesn't understand a joke, no amount of explanation is going to elicit the intended belly laugh. However, it's a topic central to the heart of cartooning — and therefore merits a dead frog or two.
