On his show Tuesday night, Current TV host Keith Olbermann said talk show host David Letterman was "one of the few entertainers who takes the responsibility of nightly or weekly television comedy seriously."

During Olbermann's Monday appearance on the Late Show With David Letterman, the two discussed the "Occupy Wall Street" movement for nearly six minutes.

"I love this," Letterman said. "I love people causing trouble. I love it when stuff doesn’t go the way it’s supposed to go. And largely, this is the only way we get change anymore in this country. As I’ve said a billion times now... some of the great cultural social issues in this country in the last 60, 70 years have begun via protest."

Olbermann claimed that Letterman deserved credit for the "extraordinary clarity he applies to politics and culture -- to bemoan man’s inhumanity to man."
