This is a clip from an upcoming episode of My Life on the D-List. Kathy Griffin goes to see one her idols, Lily Tomlin, and then the two go out to dinner. But the interesting part of the clip is when Griffin talks about having a ten year ban on Late Night with Conan O'Brien and how it was just lifted (I assume this was filmed before Conan took over The Tonight Show). Griffin appears tonight on Letterman's show for the first time in twelve years so that ban was lifted too.
