Truth was actually a topic in the Ricky Gervais meets ... Larry David that I was watching:
Ricky Gervais: "We're going through life compromising for the good of everyone. That's why people like yourself don't compromise in your art. That is where no one can be hurt."
Larry David: "I'm such a lier in my life, keeping things to myself, not really telling my true feelings, I feel like I wanna go completely the other way when I have the opportunity. ... If you're any good, you must have the compulsion to tell the truth."
Ricky Gervais: "Absolutely, and without guilt. This is guilt free truth."
