Last night, Keith Olbermann reincarnated Countdown on Current TV and it was pretty much the same exact show he had on MSNBC before the network gave him the boot. To call it "new" is a bit of a stretch, but Olbermann stopped by tonight's Late Show with David Letterman to promote the program and read off tonight's Top 10 list, "Reasons to Watch the New Countdown with Keith Olbermann." Video of the segment is above.
