Celebrity guests are put on the spot in the popular “Not My Job” segment of the Peabody award-winning NPR radio show.

Each week, two million listeners tune into Wait Wait . . . Don’t Tell Me! to test their knowledge of the week’s dumbest news against some of the best and brightest—panelists including author and humorist Roy Blount Jr., author and radio anomaly Tom Bodett, syndicated advice columnist Amy Dickinson (“Ask Amy”), Atlantic Monthly journalist P.J. O’Rourke, Washington Post columnist Roxanne Roberts, and other know-it-alls.

Always a high point of the show, “Not My Job” features a celebrity guest who must answer questions on a topic totally outside his or her area of expertise. Guests must also contend with not-so-helpful interjections from host Peter Sagal and the panelists, with hilarious results. Comedians Stephen Colbert (The Colbert Report) and Denis Leary (Rescue Me), actors Leonard Nimoy (Star Trek), Neil Patrick Harris (How I Met Your Mother) and Carrie Fisher, musicians Mavis Staples and Moby, Southern cook and restaurateur Paula Deen, and high-wire artist Philippe Petit (Man on Wire) are just a few of the stars who find themselves under the heat of the Not My Job spotlight.
