The Daily Show's Jon Stewart and Living Legend Liza Minnelli

Oprah talks to “The Daily Show’s” Emmy-winning host and best-selling author Jon Stewart about his new book, "Earth: A Visitor’s Guide to the Human Race." Jon shares his take on the “Oprah” show’s influence on our culture, and the comic genius puts his own signature spin on some recent newsmakers just for us. Then, living legend Liza Minnelli takes center stage for a rare performance of her most classic hits, including one from her new CD, “Confessions.”
