David Letterman announced yesterday that after 31 years of hosting Late Night, he is retiring next year. Is he the greatest late night host ever. I am a Johnny Carson guy and feel no one has ever come close to Johnny. Letterman was always my second favorite though. Jay Leno had a very long successful run and I think Jimmy Fallon is off to a great start.
