… ‘Wit’s End’ Review: You’ve Got to Be Kidding - WSJ. (Hat tip, Dave Lull.)

Although Mr. Geary keeps returning to the subject of puns and their capacity to fold “a double knowledge into words,” he ranges wide. One moment he’s explaining the neuroplasticity required by London cab drivers who from memory navigate the city’s convolutions, the next he’s referencing a Buster Keaton sketch, illuminating the concept of Witzelsucht (a pathological urge to crack jokes) or citing Aristotle’s belief that wit is educated insolence.
