There are too many people, that's why we have global warming. We have global warming because too many people are using too much stuff.

I mean, there's no point in sittin' around and cryin' about spilt milk. Gotta move on.

The next most dangerous thing [after nuclear proliferation] is probably... global warming, and then, right behind that are overpopulation -- we need to get serious about family planning-and trying to alleviate poverty, to get clean, renewable energy, probably with solar panels to the billion and a half people in the world who don't have access to electricity.

Most of the people will have died and the rest of us will be cannibals.

I regret that I wasn't more successful with my marriages, but it is what it is.

I think we've already voted at the U.N., in the Security Council, to get rid of nuclear weapons. Let's get rid of them. Let's get rid of ours and then Iran will stop, I believe. And so everybody else will, because if everybody doesn't have them, then we're safe, at least safe from a nuclear attack.

I haven't been in a store to buy anything for five years.
