Scott Aukerman is the co-creator of hilariously awkward talk show Between Two Ferns with Zach Galifianakis.  He talks about expanding the Ferns universe for Between Two Ferns: The Movie, how he and Zach improvised the entire film, and what it was to direct his hero David Letterman.  Scott reveals how Between Two Ferns was born out of his and Zach's love of bad cable access programming, why actual ferns were so essential to the look of the show, and how they managed to snag President Barack Obama as a guest.  Plus we celebrate 10 years of Scott's podcast Comedy Bang! Bang! Between Two Ferns: The Movie comes out on Netflix beginning this Friday, September 20.  Subscribe to Scott’s podcast Comedy Bang!
