I once asked the most fabulous couple I know, Madonna and Guy Ritchie, how they kept things fresh despite having been married for almost seven months. 'It's a job, Al,' Guy told me. 'We work at it every day.'

Harvard's Kennedy School of Government asked me to serve as a fellow at its Shorenstein Center on the Press, Politics, and Public Policy. After my varied and celebrated career in television, movies, publishing, and the lucrative world of corporate speaking, being a fellow at Harvard seemed, frankly, like a step down.

My dad never graduated high school. He was a printing salesman. We lived in a two-bedroom, one-bath house in St. Louis Park, Minnesota. We weren't rich - but we felt secure.

You know, Lincoln was funny. I don't think F.D.R. was very funny. But Lincoln was funny. Lincoln was really funny. But I think you should get elected first, and then show that you're funny.

My dad always told me to stand up to bullies, and Bill O'Reilly is kind of a bully, and he's the kind of kid who hits other kids on the playground. And when you hit him, he runs to the teacher and says, 'Teacher, sue him.'

If we have George W. Bush as president, we're going to go back to the kind of policies we had when his father and Ronald Reagan were president.

I hope you realize, in a democracy, laughter is assent.
