Steve Martin breakdowns Steve Martin (link via Smithsonian.com)
In a college psychology class, I had read a treatise on comedy explaining that a laugh was formed when the storyteller created tension, then, with the punch line, released it. I didn't quite get this concept, nor do I still, but it stayed with me and eventually sparked my second wave of insights. With conventional joke telling, there's a moment when the comedian delivers the punch line, and the audience knows it's the punch line, and their response ranges from polite to uproarious. What bothered me about this formula was the nature of the laugh it inspired, a vocal acknowledgment that a joke had been told, like automatic applause at the end of a song.
