Penn & Teller: Bullshit! (2003–2010)
FAQAdd to FAQ
Penn: "You'll notice more obscenity than we usually use. That's not just because it's on Showtime and we want to get some attention. It's also a legal matter. If one calls people liars and quacks, one can be sued and lose a lot of one's money. But "motherf*ckers" and "assh*les" is pretty safe. If we said it was all scams we could also be in trouble but "bullsh*t!", oddly, is safe. So forgive all the "bullsh*t" language. We're trying to talk about the truth without spending the rest of our lives in court because of litigious motherf*ckers."
