Katie Couric has just four more “Evening News” broadcasts left. As she announced last night that next Thursday will be her final broadcast, Couric added, “That night we’ll take a look back at some of the amazing stories we’ve covered over the past five years.”

As Couric was announcing her departure date, a few blocks away David Letterman was including her in his monologue. “Katie Couric… after five years of being the face of CBS News, is leaving … So that means that here at CBS, Andy Rooney is now the perkiest person.”
