Flight of the Conchords
From HBO (and to a greater extent, New Zealand) comes the "new" show Flight of the Conchords. Like most new things on television, Flight of the Conchords (Bret McKenzie and Jemaine Clement) have been around for quite some time. They've already had an HBO special (YouTube "Rhymenoceros" and revel in the glory), and, of course, have been performing in the U.S., New Zealand and many other places around the world. They're basically like a more polite, less metal, version of Tenacious D. The clip above is taken from their first episode, which airs on HBO on June 17th at 9:30 central time (10:30 eastern).
