It's a bit jarring to see Conan O'Brien without his beard, which is weird, because he only had it for about a year since his break from NBC (and then also during the WGA strike).

On Conan's first full night back to being clean-shaven, he welcomed Steve Martin to his TBS late-night show. Martin delighted with stories about his new bluegrass album, making a movie about competitive bird-watching, and also granting O'Brien's wish to compete in "Dueling Banjos." Of course, there was a catch. A funny, offbeat catch. The whole chat and performance is in this clip. Roll it!
