This week we mix it up with anchorman and scorekeeper of NPR’s “Wait Wait… Don’t Tell Me!” Bill Kurtis. He talks about his delicious and nutritious Tall Grass beef franks. Plus, we grill “Gulp” author Mary Roach about the benefits of juicing and extreme chewing. And we learn the secrets of eating like a movie star with actor John Turturro who wrote, stars and directs the new movie “Fading Gigolo.”
