Vanessa Williams lost her crown, but the details were lost on most of us. “You Must Remember This” and guest host Cassie Da Costa explore colorism in Hollywood through the story of the beauty queen and her tarnished crown. And across the world in Marrakech, a socialite stiffs one of the world’s most expensive hotels for the bill, leading to a splashy court case and a diversionary tale of Manhattan grift, told by Andrew Jenks and one of the victims herself on his show, “What Really Happened?” Gina Grad and Teresa Strasser explore the best of this week’s podcasts through clips and discussion on this podcast about podcasts. It’s like a book group, without all those musty books.
