Conan O'Brien on Johnny Carson: Rule number one is just be yourself. And that's actually the first thing, when I got the Late Night Show -- I bring them up now because they just did this great documentary about Johnny Carson -- one of the first people I talked to was Johnny Carson and he said, "Just be yourself." He said "It's the only way it can work." He didn't say it would work, because he's being honest; he didn't know me. You might be yourself and it would be terrible. But he said, "Be yourself, it's the only way." There's an honesty to that. I do think that that's a little bit timeless.
