When I first agreed to do 'Shark Tank,' they asked me to wear a suit, and I was just like, 'No. I can't. It'll end my career.'

At my age, no one is married, no one has kids, no one has a career.

We virtually never feel our age, but thinking that we should can lead to disaster.

There are signs that the age of petroleum has passed its zenith. Adjusted for inflation, a barrel of crude oil now sells for three times its long-run average. The large western oil companies, which cartellised the industry for much of the 20th century, are now selling more oil than they find, and are thus in the throes of liquidation.

No, but way before that, I've been doing little dances in movies for years. Yeah, that was an amazing chance. You know, at my age to be able to do a music dance video, very unusual.
