Brian Williams is by far and away the best regular guest on “The Daily Show.”  Williams makes the news all boring on NBC with his gravitas, but he’s actually got a very dry sense of humor and an acerbic wit.  On last night’s show, Jon Stewart grilled him about the journalistic ethics — or lack thereof — in trying to land an interview with South Carolina Gov.

Stewart: Walter Cronkite was a giant in the industry.  Is that a man you looked up to?  Is that a man who…
Williams: The guy I wanted to be when I was a kid.
Stewart: Really?
Williams: It was like Carrot Top to you.

Best thing on TV last night, hands down.  And that’s saying a lot, because “Dating in the Dark” was excellent.  So congratulations, Brian Williams and Jon Stewart.  You bested the show about people making out in a dark room.
