 We'll continue with The Odd Couple in a moment. First, we'll hear from playwright Neil Simon about The Odd Couple and the art of writing the gag line. How do you write a gag line? Is there a specific technique? No. You either think of it or you don't. And you don't look for it. It just comes up. I think with all good writers, with Larry Gilbert, with Mel Brooks, you're writing something and something occurs to you. There was one line in The Odd Couple.
