From an inauspicious beginning performing comedy routines in the back of a burger joint in New York, unorthodox stand-up star Zach Galifianakis has made a splash on the scene with his inimitable brand of humor. In this live show filmed at San Francisco's Purple Onion nightclub, the versatile funnyman serves up a healthy dose of his signature wit.

Galifianakis dreamed of becoming a star. But when Will Ferrell discovered his public access TV show, 'Between Two Ferns' and uploaded it to Funny or Die, Zach became a viral laughing stock. Now Zach and his crew are taking a road trip to complete a series of high-profile celebrity interviews and restore his reputation.
