Long haired comedian on Comedy Central Presents?

I saw a guy on Comedy Central Presents like two weeks ago. He had long hair and was kind of a hippie/rocker guy, he had a goatee kind of beard. He told a joke about how you could get him and his friends into gas chambers like the Holocaust with the promise of an AC/DC concert and how they would just get high off of the gas. He also said the people he trusts most wear Iron Maiden shirts. Its a long shot but does anyone know who it is?
