Interviewer: Can you explain jazz?
Yogi Berra: I can't, but I will. 90% of all jazz is half improvisation. The other half is the part people play while others are playing something they never played with anyone who played that part. So if you play the wrong part, its right. If you play the right part, it might be right if you play it wrong enough. But if you play it too right, it's wrong.
Interviewer: I don't understand.
Yogi Berra: Anyone who understands jazz knows that you can't understand it. It's too complicated. That's whats so simple about it.
