Letterman Mocks Leno, NBC On 17th Anniversary Of 'The Late Show' (VIDEO)

Last night, David Letterman celebrated the 17th anniversary of "The Late Show" by taking a few funny jabs at Jay Leno and NBC. As Letterman reminded the audience that it was the anniversary, he said the show began 17 years ago last night, "right after Johnny Carson had been Leno-ed." He followed up with his best Leno impression, of course.

Letterman then moved on to say some cynical remarks about his old network, NBC, after previously griping about the show's lack of Emmy attention in the beginning of his monologue. He started to say how nice the people at NBC were, implying that they sent him an anniversary gift out of the blue, but ended with "Yeah, the executives over at NBC today faxed me the finger."
