Comedy group from the late 60's/early 70's who made such classic albums as "Don't Crush that Dwarf, Hand me the Pliers" and "All Hail Lennon and Marx"
(with photos of John Lennon and Groucho Marx on the cover). Off-the-wall; very drug inspired and fun to listen to while doing drugs. College kids from that era still quote them to this day; i.e. "United Snakes of America", "Don't eat with your hands, use your entrenching tools." Most fun when listening with Koss headphones.
