I started to make harder jokes before anyone else did. And the producers would get anxious. They'd say, 'That's a little bit hard-edged, isn't it?' And I'd say, 'Let's just try it and see how the audience reacts. If they don't like it, let's cut it out.' And the audience roared with laughter, so I learned you could do this harder humor and people loved it.
Now most people do not want an ordinary life in which they do a job well, earn the respect of their collaborators and competitors, bring up a family and have friends. That's not enough any more, and I think that is absolutely tragic - and I'm not exaggerating - that people feel like a decent, ordinary, fun life is no longer enough.
I think you can write very good comedy without a partner, but what I love about it, working with a partner, is that you get to places you'd never get on your own. It's like when God was designing the world and decided we couldn't have children without a partner; it was a way of mixing up the genes so you'd get a more interesting product.
