Hi, I'm Xing Xing.
And I'm Simon Jack.
And together we host Good Bad Billionaire,
the podcast exploring how some of the world's richest people made their fortunes.
And we are back with a brand new season of Billionaires.
Yes, movie megastar, Arnold Schwarzenegger, America's richest self-made businesswoman,
Diane Hendricks, and co-founder of Snapchat, Evan Spiegel, to name just a few.
And we're asking you, the listener, to decide if they're Good Bad or just another billionaire.

There are few things as familiar as pepper.
People consume about three quarters of a million tons of it every year.
We sprinkle it on everything, grind it if we're feeling classy.
So it's kind of amazing how little we know about it.
What is pepper?
I have no idea.
No idea.
