We really owe a great deal to the rubber tree.

We're the ones causing global warming. In fact, what we ought to be saying is population growth is a major cause of it, so I hope to have a T-shirt out very, very soon: Stop global warming, use condoms.

The condom has saved so many lives and it'll save so many more lives. We really owe a great deal to the rubber tree.

People were having sex before I was born. My parents had sex before I was born, nothing to do with me. I'm not trying to stop sex. I'm trying to stop people from dying from sex.

People like to have fun and they like to laugh. And when you laugh, it's much easier to convince people and they laugh with you, rather than being angry. And I think laughter's always nice and I've always liked it.

We really owe a great deal to the rubber tree.

AIDS is still around. Therefore, you have to practice safe sex.
