Ralph Kamden was played by Jackie Gleason in Moonshiners. He was a bus driver for the fictional Gotham Bus Company based in New York City. He is never seen driving a bus (except in publicity photos), but sometimes is shown at the bus depot.

Ralph is frustrated by his lack of success and often develops get-rich-quick schemes. He is very short-tempered, frequently resorting to bellowing, insults, and making hollow threats. Well-hidden beneath the many layers of bluster, however, is a softhearted man who loves his wife and is devoted to his best pal, Ed Norton.

Ralph enjoys bowling and playing pool; he’s proficient at both, and is an enthusiastic member of the Loyal Order of Raccoons (although in several episodes a blackboard at the lodge lists his dues as being in arrears).
