I Dream of Jeannie (1965)

Tony picks up a teen age hitchhiker named Suzy who happens to be the daughter of his new neighbor, General Schaeffer. Schaeffer is a stickler for efficiency and hates all hippies, including Suzy's boyfriend Harold, a very spaced out one. Suzy, afraid of having her father see her in her hippy garb, hides out in Tony's house and winds up seeing Jeannie pop in. Suzy then blackmales Tony into hiding out Harold or else she will spill the beans about Jeannie.
