Yesterday, Craig Ferguson announced his departure from CBS's The Late Late Show after ten years as host. Addressing the news during his taping on Tuesday, Letterman, whose Worldwide Pants produces Ferguson's show, offered a nice little tribute to the guy in the next time slot. "His show was unlike any other late-night show, and I'm telling you, to be unique in the world of television: virtually impossible. So, congratulations to Craig on a great run, and we all wish him well." Very sweet.
