If you’re my age, you know what it was like to watch TV shows such as “My Three Sons” when they were originally broadcast in the 1960s and ‘70s. (And if you know my age, keep it to yourself. The truth hurts!) Although I was the oldest of three siblings, I have to admit I always identified best with the youngest of actor Fred MacMurray’s three sons on the show, Ernie, played by my guest today, Barry Livingston. Ernie wore the glasses, as did I, had issues with his teeth, as did I, and always seemed a bit awkward, as did I. And where he had Uncle Charley to keep him and his two older brothers out of trouble, I had my not-quite-as-grumpy grandfather. It was, in TV terms, a kinder, gentler time, even as the Vietnam war, civil rights and the counterculture revolution raged in the real America. Barry co-starred on the show with his older brother, Stanley, who played middle-son “Chip.” BARRY LIVINGSTON podcast excerpt: "I'll tell you that in the 1960s I put something a little different in my pipe than what Fred MacMurray was smoking."  Since those days, Barry Livingston has remained front and center in pop culture. He has a role in ABC’s hit drama, “Castle,” and plays a part in Ben Affleck’s new film, Argo. He’s also appeared in episodes of “Mad Men,” “Two and a Half Men,” and movies such as Horrible Bosses and David Fincher’s film, The Social Network, about the origins of Facebook. He’s also written a book, "The Importance of Being Ernie: From My Three Sons to Mad Men, A Hollywood Survivor Tells All."   Barry Livingston •
