I'm really, really late posting this. If I'm not mistaken, it dates back to the July 21 edition of The Late Show with Stephen Colbert, back when they were broadcasting live every night after the Republican National Convention. But there's actually something to be said for watching it now, with the benefit of some historical perspective.
Stewart's time away from his show hasn't diminished his talent for hilarious and spot-on commentary, and Colbert's not bad either. It's worth 13 minutes of your time. Actually, it's worth at least half an hour of your time, but it only runs 13 minutes and change.
