The world is a slightly better place for having improvisation in it than it was before. There's something about it that says something positive about the human spirit, that a bunch of people can get together and by following a few simple traffic rules can create art and can entertain an audience and can thrill and exalt each other.

The kind of improv that I'm particularly addicted to is the kind that... aims at creating a momentary, fragmentary experience that has a totality to it. It's kind of like fireworks. It's the more ephemeral of art forms - once it's gone, it's gone, baby.
