In the Nerdist Podcast episode #195, Penn doesn't just discuss life behind the scenes of Las Vegas, but he reveals how "The Amazing" James Randi has had a profound influence on him and a little about what it means to be a skeptic. He also talks about the skeptical movement and the the work that the James Randi Educational Foundation (JREF) does with their annual conferences celebrating science, skepticism and critical thinking called, "The Amazing Meeting" (TAM).
Oh, and a spoiler alert...
he also explores the mind of a psychopath through Dean Martin, and argues why it is advantageous in Hollywood.
