The basic premise: a hillbilly from Bugtussle, Tennessee or Arkansas, Jed Clampett (Buddy Ebsen), becomes unbelievably rich when oil is discovered on his property, so he moves to a mansion in Beverly Hills, along with his crotchety mother-in-law Granny (Irene Ryan), his daughter Ellie Mae (Donna Douglas), and his dumb-lunk nephew Jethro (Max Baer Jr.).
Though they became marginally assimilated after nine years, they still wore hillbilly clothes, ate possum pie, and referred to their swimming pool as a "cement pond." Plots usually involved big city types trying to dupe and manipulate them, but their backwoods wisdom, orneriness, or dumb luck win out in the end.
The message: big city life is dehumanizing. Only in the country can real be real.
Other plots involved Ellie Mae's dating, Jethro's get-rich quick schemes (odd, since he already was rich), and Granny's dislike of all things big city.
Bonding was also rather uncommon. Most of the primary relationships were platonically male-female: Jed and Granny, Ellie Mae and Jethro, bank president Mr. Drysdale and his secretary, Miss Hathaway (Nancy Culp, who incidentally was gay in real life.)
But gay-vague was everywhere.
1. Mr. Drysdale's son, Sonny (Louis Nye) is sophisticated, well-educated, and not interested in girls. His parents keep trying to hook him up with Ellie Mae (so he will eventually inherit the Clampett millions), but he will have none of it. He and Ellie are just friends.
2. Hollywood star Dash Riprock (Larry Pennell), a parody of Rock Hudson, is handsome, suave, and not interested in girls. He vaguely courts Ellie Mae, but his heart isn't in it, regardless of how much his studio pushes them together.
Apparently the producers thought it hilarious to keep having Ellie Mae run into men who were not interested in girls.
3. Jethro had a "twin sister," Jethrine. She stayed back in the hills, and didn't show up often, but when she did, it was obvious that it was Jethro in drag. I got the distinct impression that everyone was just playing along, responding to his drag persona as if she was a different person.
