From an Interview with Ricky Gervais in the Onion

AVC: Do you think people sometimes laugh at things for the wrong reasons?

RG: I just don't think there's any pleasure in getting an easy laugh. There can be no reward. You stand at the back of a chain comedy club, and those guys come out and they're going, "Ha! What's going on with Scooby-Doo? A talking dog!" And I want to shout, "It's a kids' program!" What vein of comedy gold have they really hit upon there? Then some other guy goes, "Ugh, the '70s, haircuts were different, weren't they?" I want to go, "Well, yeah, but I don't know what you've done there." I don't get observational comedy. It's observational, but they've just left out the comedy bit. And these people are cracking up! They couldn't laugh any more. So you think, "Why would I try and make those people laugh? I don't need to make them laugh. They're happy enough. I'd probably just spoil it for them." I'm aiming at someone else. I'm not uptight about it. I don't want to close those comedy clubs down, I just don't want to play them.
