From Wikipedia -- Arnold Ziffel was a pig featured in Green Acres, an American situation comedy that was produced by Filmways, Inc., and originally aired on the CBS network from 1965 to 1971. The show was premised on rural American humor and featured Oliver Wendell Douglas and his wife Lisa as city-dwellers who move to the unfamiliar environment of Hooterville, a fictional farming community. Arnold was a pig, but he was treated as the son of Fred and Doris Ziffel. As evidenced by Arnold's erect ears and all white coloration, he was of the American Yorkshire breed. Arnold could do pretty much anything he wanted. He was very talented. He could write his name, change the channels on the television, and play the piano. He was an accomplished abstract painter (dubbed "Porky Picasso"), whose work, such as "Nude at a Filling Station," was banned. Arnold also attended school, carrying his lunchbox in his mouth, where he often played practical jokes on the other students. He was once drafted into the U.S. Army and even worked as a "paper pig" delivering newspapers, although he had a bad habit of throwing copies so hard and so badly aimed that he sometimes broke residential windows doing it. Arnold was also very lucky, winning a trip to Hawaii in one episode, a prize at the Pixley movie theater for having the most original costume (the theater manager said he had the best looking pig costume he'd ever seen), and a trip to Hollywood. After a screen test, he was cast in a role originally intended for a horse, but after the horse explained to Arnold that, without the job, he'd never be able to send his son to Stanford, Arnold's deliberate bad behavior led to his being fired and the horse getting his job back. Arnold fell in love with Mr. Haney's prized Basset Hound "Cynthia", but in a scene full of pig grunts and dog barks, subtitles explained that they were realizing that their love could never be. Mr. Haney then threatened to sue Mr. Ziffel, claiming that Arnold had ruined Cynthia for show as she had begun to grunt like a pig too. Some sources point out that Arnold was actually played by a piglet. Because piglets grow quickly as they become adult pigs, this would require that at least one piglet per year had to be trained for the role of Arnold during the seven years that the show was in production. In most episodes, Arnold was played by a female piglet.
