Longtime Conan writer Brian Stack worked with Andy on all three of Conan's late-night shows and played fan-favorite characters like Artie Kendall the Ghost Crooner, the Interrupter, Hannigan the Traveling Salesman, one of the Slipnutz, and more. The comedian, who now works as a writer for "The Late Show with Stephen Colbert," joins Andy Richter this week to discuss memories from the writer’s room, twenty-seven years in late-night television, the creation of Amy Poehler’s Andy’s Little Sister character, the contrast between his upbeat demeanor and dark sense of humor, and much more.
