Hank Patterson, who played Fred Ziffel on Petticoat Junction and Green Acres, was born October 9, 1888. If he were alive today, he would be 126! It seems impossible that he could have born that long ago, but apparently he was in his late 70s when Green Acres started. IMDb shows acting credits for Patterson dating back to 1939.
Fred Ziffel, of course, was the “father” of the pig Arnold Ziffel, who was treated like a human. In the clip below from Green Acres, Fred and his wife, Doris, are upset that Arnold has started to bark after forming an attachment to Mr. Haney’s dog, Cynthia.
