Petticoat Junction - Season 3 Episode 4 The Good Luck Ring

Bobbie Jo is entering an upcoming spelling bee, but it may be a losing battle against stuck up but excellent speller Henrietta Watson. Cora Watson, Henrietta's equally stuck up mother, protests Sam's appointment as judge since she feels he will be biased in favor of Bobbie Jo. As such, Oliver Douglas, is appointed the new judge. Bobbie Jo doesn't have the confidence to win, until she finds a scarab ring. Now it seems she is flooded with good luck. Slowly, the family begins to believe in the power of the ring when they too get what they want when wearing it. Uncle Joe loses the ring and buys another one. After winning the spelling bee, Bobbie Jo realizes it wasn't because of the ring.
