I went through periods where you're just sort of writing things that are supposed to be funny and things that look like a sitcom. Now we're writing about real life and things that we care about. That's one of the things that a lot of these new shows have in common, like Everybody Hates Chris -- he's writing about his life.

Also I think a lot of the pressure came from ourselves. We really cared about this a lot. When we were first starting to develop it, we came up with a few ideas and actually wrote a script for another pilot. And we liked that one too, but it wasn't personal like this one was. This one felt like something we'd write whether we had a deal to write it or not. From where I'm coming from, it was at a point in my life where I was single and thinking, 'When am I going to settle down and get married?' It was very therapeutic writing in a weird way. The real pressure was for us not to screw it up ourselves.

Great, now we've blown the series finale.

But they've been fearless about it. There hasn't been a moment of doubt or a suggestion to make it more traditional. We have no 'indignant writer' stories to tell.

But for us it was three years ago. We still miss it. We love New York so much.

We sort of look at our years at 'Letterman' as comedy grad school. I don't mind seeing jokes and hearing the laugh track because that was our bread and butter for a long time, just making an audience laugh ... There's no better feeling than having a crowd there and hearing a laugh.
