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.

I think the biggest wrestling match-up I have is how to respond to the word "quirky." Or the alternate, "nerdy." Both are essentially benign to the reader, but if you're a writer just sort of involved in your creative process, they seem like very small motivations.

Between me and my wife, there's this joke where I'll be doing some fun interview, and I'll get off the phone and be like, "That guy was an idiot." A lot of times, interviews are like being asked a list of questions. Invariably, there will be this part where they think you're a writer for Letterman: "Just off the top of your head, tell me the 10 most influential bands on you." And you're actually asked to come up with a spontaneous list. It's like, "Dude, I'm not living in High Fidelity."

A lot of times I'll post things on Facebook, and the immediate response will be like, "Stick to the music!"

There's so many simple things that can be done to change our carbon footprint, and to reduce our carbon footprint.

People love fact-based songs, which is a very funny idea.

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.
