Tennessee Tuxedo was a popular, semi-educational animated cartoon show that originally aired on CBS from 1963 to 1966. It was produced by Total Television, the same company that produced the earlier King Leonardo and the later Underdog.
It revolved around the title character, a penguin (voiced by Don Adams of Get Smart fame, who would voice Inspector Gadget twenty years later) and his best friend Chumley, a walrus. The pair lived (against their will) at the zoo, under the control of the ill-tempered zookeeper, Stanley Livingston (sic) (an obvious pun on the missionary David Livingstone and journalist Henry Morton Stanley).
Tennessee and Chumley regularly escaped from the zoo, only to find trouble in the outside world. When faced with more trouble than they could bear, the pair would turn to their friend, a college professor named Phineas J. Whoopee (voiced by Larry Storch, later seen on F Troop). "Mr Whoopee", as he was known, was extremely knowledgeable on all subjects, and would frequently lecture the pair on such diverse topics as the physics behind the hot air balloon, to how musicians become popular. His lectures were illustrated and animated on the Three Dimentional Blackboard (3DBB for short) he would retrieve out of an avalanche of junk from his overstuffed hallway closet. The pair would then attempt to use their newly-gained knowledge to get out of the trouble they had created, but would invariably end up in more trouble with Stanley Livingston, who typically punished them by making them scrub pots and pans for six months.
