Could somebody help?

Could somebody help settle an argument with my wife? There’s this guy, Bill Maher who’s on Larry King once in awhile. He expounds on world and political events. Well here’s the thing. My wife says that Bill Maher talks about politics and such because he actually believes he possesses wisdom and insight; he actually believes that what he says is important. I say that Bill Maher tries to sound intelligent and relevant because it’s part of his comedy routine. It's like satire or sarcasm - very funny stuff. Who’s right? Is Larry King laughing with Bill Maher or at him? I pick the former. My wife picks the latter.
