Somebody has to wear the black hat and give the audience someone to shake their fists at. They want someone to hate. And if that's what you want to pay me to do, I'm happy to do it!
For me, something will come in my head and I'll either end up calling my cell phone to record it, or I'll just pick my guitar up and see what comes out. Sometimes it sucks, sometimes it doesn't. So there's really no set method behind it.
Being president is like being a jackass in a hailstorm. There's nothing to do but to stand there and take it.
