Penn & Teller: Bullshit!2003

Penn Jillette:
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***ers" and "a**holes" is pretty safe. If we said it was all scams we could also be in trouble but "bullshit!", oddly, is safe. So forgive all the "bullshit" language. We're trying to talk about the truth without spending the rest of our lives in court because of litigious motherf***ers.
