We don't know if Cheeta, in his ghostwritten memoir, Cheeta: My Story, will be revealing whether or not he ever touched Maureen O'Sullivan inappropriately (like children, animals can get away with that), but it's bound to be a good read nonetheless. The now-graying 75-year-old chimp starred in a dozen Tarzan movies, outliving his costars, and retired from films in 1967, after presumably having a speaking part in Dr Doolittle. Said the oldest living chimp's publisher, Dan Halpern, "Tarzan and Jane's best friend still loves the ladies. In 2006, he was seen canoodling with legendary chimpologist Jane Goodall. Cheeta, who's been known to watch his old movies with his grandson, promises to dish on his career (and the likes of Errol Flynn), as Hollywood's most famous swinger."
