Arnold Ziffel is a fictional pig featured in Green Acres, an American situation comedy that aired on CBS from 1965 to 1971. The show is about a fictional lawyer, Oliver Wendell Douglas, and his wife, Lisa – city-dwellers who move to Hooterville, a farming community populated by oddballs. Arnold is a pig of the Chester White breed, but is treated as the son of farmer Fred Ziffel and his wife, Doris, a childless couple. Everyone in Hooterville accepts this without question. Arnold's first TV appearance is in the second season of Petticoat Junction, in the episode "A Matter of Communication".
