This is Bob Mankoff’s time. The cartoon editor of the New Yorker has just published a memoir: “How About Never. Is Never Good for You?”  He’s a regular on WNYC’s The New Yorker Radio Hour. And he was featured in the documentary  “Very Semi-Serious,” which debuted on HBO last week. Recently our Bob sat down with their Bob to talk about art, life, cartoons, and much, much more.
