Take a look around you. Unsettled or distressing times spawn a push back in people. It’s a natural reaction, especially in this country. Comedy thrives in periods of uncertainty. Hell, we even have a cable channel now dedicated to this style of entertainment. I wonder if that indicates we’re in an ongoing epoch of apprehension? Oh well. I’ve read a number of examinations over the years on what and why comedy does (or doesn’t) work. Two aspects draw me. Jokes, and their telling, can date quickly. What tickles today may fall flat tomorrow. Second, insightful jests can be enough to cut the comedian and/or the audience right down to the core.
