Secrets, Jandek, Underground Railroad

Kurt and special guest Teller, half of the magic and comedy team Penn & Teller, talk about secrets, with stories about the search for the real identity of a cult-musician called Jandek and about the secret coded messages of escape and survival sewn into quilts during the era of the Underground Railroad. And Paola Antonelli, design curator at the Museum of Modern Art, looks at the ever-changing style and technology of the sneaker.
