While filming the country mockumentary film "Dill Scallion" in 1998, Koechner befriended actor/comedian Dave 'Gruber' Allen, and eventually began performing as the comedy duo, "The Naked Trucker & T-Bones Show", a live musical comedy act. The act became a hit at Hollywood clubs such as Largo, and Allen and Koechner were invited to open for Tenacious D. In 2007, Koechner and Allen created and starred together in a "Naked Trucker & T-Bones Show" sketch comedy series that ran for one season on Comedy Central.
