I feel like the future is unwritten. So many of the things that we write now haven't been about educating people on the environment, they've been about disseminating facts. But I feel like it could be productive to write something that explored directly the idea of fragility.

It's hard to tell a shallow person that they should care more about the feelings of the awkward and the alienated.

There have been times I wanted to cry on interview, but it hasn't been because that's what they're trying to conjure. No. I think you have to graduate to some higher level of TV IQ for people to actually want to see you cry.

So we've done science songs. We've done historical songs. A lot of people would like us to do more historical songs. Our history record would probably be like the people's history of the United States, set to music.

If you're looking at the array of performers, there's just a lot of people that it's about getting closer to them. That's not really our focus. It's funny, with the kids' stuff, we really sell ourselves as the MC, but it's much more like we're Ed Sullivan than we're like Sting. We're just the presenters. And that's an idea that we're very comfortable with.

Bill O'Reilly knew he could just filibuster and enjoy all the airtime that a full interview would give him, and then also grab the sensationalist headlines that he enjoys creating. He used this as fodder for his show for weeks. I wouldn't want to be on the bad side of Bill O'Reilly. But then again, maybe I am now. By giving this interview.

There is a fact-based belief system available to you if you want to believe in facts. But this is the weirdest time. I mean, after Nixon I thought nothing could be weirder. Then there was Reagan, and after Reagan I thought nothing could be weirder. Then there was Bush and Bush's son, and it all just seemed like nothing could be a badder joke than George W. Bush. And now we're here. It seems to just yo-yo around, but hopefully we'll get to another level.
