Chuck Klosterman wrote a wonderful essay (it's in his collection "Eating the Dinosaur") about laugh tracks, and more broadly, about the way we use laughter. His thesis was that, especially in the mundane interactions among strangers that populate daily (US) life, laughter is a nearly continuous stream that reassures everyone that both they and everyone else around them know what's going on.

Next time you're in a conversation with a group of people you don't know, stop and listen for the laughter - it will be hard to hear because you're so used to tuning it out, but it will be shocking in its frequency when you finally pick up on it. (NB: pointing the laughter out is a good way to alienate yourself from strangers.)
