On Tuesday night's "Late Show," a retiring David Letterman had one more goodbye to make: to "The Late Late Show's" Craig Ferguson.
"(It's) too bad," Letterman said of Ferguson's Monday announcement that he was leaving his CBS gig to pursue other projects. The comedian had been hosting the show since 2005.
"His show was unlike any other late night show," Letterman went on. "And I'm telling you, to be unique in the world of television is virtually impossible. So congratulations to Craig on a great run, and we all wish him well."
Interestingly, one of Letterman's recent guests was the very guy whom some are speculating could become Ferguson's replacement.
"The Soup's" Joel McHale, who'll host this weekend's White House Correspondents Dinner, has been pegged as a possible successor for CBS' "Late Late Show," but McHale has said that no one's reached out to him.
"No one's called," he told Howard Stern on his Sirius XM show Tuesday. "I don't think I could even do it with (NBC"s) 'Community.' I'm under contract; I don't think I legally could."
With or without a replacement, Ferguson is planning to depart CBS at the end of this year.
