Petticoat Junction is an American situation comedy. The series is one of three interrelated shows about rural characters created by Paul Henning. The characters "seem" to go to Hooterville for some goods and services, including high school and the hospital, but prefer Pixley for supermarket shopping, beauty parlors, and movies. The petticoat of the title is an old-fashioned garment once worn under a woman's skirt. The opening titles of the series featured a display of petticoats hanging on the side of the railway's water tower where the three originally teenage daughters are apparently bathing in the nude or skinny-dipping. In fact, the show's opening theme contains a hint of sexual innuendo in the line, "Lotsa curves, you bet, and even more when you get to the Junction." This is an obvious double entendre referring to both the train tracks and the Bradley daughters. However, as Linda Kaye states on the official season one DVD set, the name of the town Hooterville was not a reference to the slang term "hooters" meaning breasts, because that term was unheard of in the 1960s.
