The name Jonathan Goldsmith might not immediately ring a bell, but his TV persona — the "Most Interesting Man in the World" in a long-running series of commercials for Dos Equis — probably does. You know, the guy from the ads that claim "his charm is so contagious, vaccines have been created for it." On Friday, Goldsmith discusses his new book, Stay Interesting: I Don't Always Tell Stories About My Life, But When I Do They're True and Amazing. The 78-year-old writes that he was practically living out of his truck when he auditioned for the part of the suave, older man, which he landed by mimicking Fernando Lamas. Goldsmith played the role for 10 years and became so popular he was invited to President Obama's 50th birthday party at Camp David and had celebrity fans like Michael Jordan asking for his autograph. In his memoir, Goldsmith recounts how he spent decades as a struggling actor in Los Angeles and New York, his friendship with Dustin Hoffman, affairs with one of Groucho Marx's wives and Gilligan's Island's Tina Louise, and even that time he dated Judy Garland.
