I was on my way home on a Friday afternoon. I didn't know who the hell this guy was.

I told him, look, I can't hear you, I have the top down on my car, I'll call you back when I get home.

So I called back and it was a fax number. It gave me that REE! ring. And I said, right, a billionaire with a fax number. That sounds about right to me.

So I think I went and had a beer and about thirty minutes later I get an angry phone call back from him…

"Hey!" he said. "You didn't call me back!"

I said, "Yeah I did. I got your fax machine."

"Oh. OK. I'm sorry. That's right."

He starts to tell me this idea he's got. He says the same thing today that he said eighteen years ago.

He says: "I want to make humanity a multi-planetary species. I made all of this money. I'll be damned if I waste it drinking Mai-Tais on the beach. Or pissing it away in some other venture. I want to do something meaningful with it."
