Trivia for
"Green Acres" (1965)
Adapted from the radio show, "Granby's Green Acres", which was on the air around 1950.
Creator Jay Sommers wrote extensively for "Petticoat Junction" (1963) in its second season (1964-65), and these un-syndicated shows feature the first appearances of Doris (then "Ruthie"), Fred, Newt and even Arnold the Pig the year before Acres went on the air.
The first Arnold was a male. The others - 2-4 a year - were females.
Arnold the Pig was the only cast member of the cast to win an award for a performance in a sitcom. He won the coveted "Patsy" Award, in 1967, which is given to the best performance by an animal.
