I know how sobering and exhausting parenthood is. But the reality is that our children's future depends on us as parents. Because we know that the first years truly last forever.

You never know if anything is going to stand the test of time or going to be successful.

I guess as I get older, I'm kind of getting drawn to the things that I really love the most, which is trying to figure out ways of blending politics with humor, and making it interesting. So I don't know if anybody's interested in this stuff, but I like it, so I get involved with it.

As you get older, all those dumb clichés, they're all true. You only have a certain amount of time left, and you should only spend it doing the things that you want to do. It's all true.

Albert [Brooks] was rare in that he could make adults laugh. He was a prodigy. At age 15 and 16, he could make my dad laugh uncontrollably.

Yeah, but here's the thing, if you've got actors who are used to that, and that's what they like to do, they're all good improvisers and they're all people that feel comfortable doing that, then you know, it's not that big of a deal. It's what you do.
