When you don't know what you're talking about, it's hard to know when you're finished.

The only valid censorship of ideas is the right of people not to listen.

So it - we have one enduring, uh, idea that will always live on with the Smothers Brothers, that 'Mom always liked you best.' We're the universal, uh, feeling that every child, every sibling has had somewhere along the line. Or, 'Who did she like best?' And that became kind of a little mantra.

We weren't radical chic. Jane Fonda embarrassed me. We belonged to no political parties. Basically, we were vaudevillians.

We were against the war in Vietnam and for voter registration and social issues. Everybody has their choices, and the obligation of a comedian is first to entertain. And if you're so inclined, and you have some bigger thought, make sure you express it, because that's a gift.

Every day I think, 'Gosh, I wish I could be like George Carlin, Bill Maher: I want that edge.' But every time I start to get that edgy thing, I get kind of mean.

No comedian's wife thinks he's funny. The first few years of the marriage, maybe. I was funny as hell the first couple of years.
