Last night on The Daily Show, Demetri Martin appeared as the new youth correspondent. It doesn't mean he'll stick around - off the top of my head I can think of five who only made a handful of appearances - but I hope he continues with his "Trendspotter" segments. It was funny and very much in the vein of his stand-up work. The show repeats today at 9 AM, 1 PM, and 7 PM (CST), catch it if you can or it might be added to the online archive (if not there, clips are often available elsewhere).
Previous post about Demtri Martin (and where is that comedy album he was taping?)
UPDATE: The Trendspotting segment is available here.
