This amusing chimpanzee named Cheeta became famous after appearing in the Tarzan movies released between 1930 and 1940 where he played Tarzan’s loyal companion — who in fact was never mentioned in the novels that were used as an inspiration for the movies. Then, in 1960, he retired to an animal sanctuary where he enjoyed watching sports on TV, listening to music, and behaving badly from time to time. He died from kidney failure when he was believed to be 80 years old.
