"Penn turned to me "Do I have to call him 'Your Majesty' or any of that shit? And what about bowing? I have to bow? We don't bow in America. I won't get put in the Tower of London or anything?" I reassured him on these points. No Highnessing, no kowtowing. At last the Prince reaches Penn, who immediately falls almost prostrate to the floor. "Your Majesty Highness, Your Royal Sir…" and so on and so forth, babbling like a gibbon on speed. The Prince passes on to me and whoever was the other side of me without turning a hair. Seen it all before. After he had gone, I watched Penn, an enormous man, crouching on the floor, rolling about, beating the planks of the stage, sobbing, stuffing his fist in his mouth and moaning up to the fly-tower: "Why did I do that? What came over me? What power do they have? I betrayed my country!"

“There Is No God" on This I Believe”

“The question I get asked by religious people all the time is, without God, what’s to stop me from raping all I want? And my answer is: I do rape all I want. And the amount I want is zero. And I do murder all I want, and the amount I want is zero. The fact that these people think that if they didn’t have this person watching over them that they would go on killing, raping rampages is the most self-damning thing I can imagine. I don't want to do that. Right now, without any god, I don't want to jump across this table and strangle you. I have no desire to strangle you. I have no desire to flip you over and rape you.”

“Rabbi Daniel Lapin: Here's a really blunt question: would the world be a better or a worse place if a billion Muslims became evangelical Christians tomorrow?”

“I can read ideas from all different people from all different cultures. Without God, we can agree on reality, and I can keep learning where I'm wrong. We can all keep adjusting, so we can really communicate. I don't travel in circles where people say, "I have faith, I believe this in my heart and nothing you can say or do can shake my faith." That's just a long-winded religious way to say, "shut up," or another two words that the FCC likes less.”
