Thicker than Water (1973)

Sensible Nellie Paine and her womanizing brother Ernie were promised $75,000 each if they moved back home to live with their elderly father Jonas and run the family business, Paine's Pure Pickles, for five years. The only thing the siblings have in common is they both hate pickles. Jonas shows no signs of dying soon, and enjoys seeing his grown children squabbling.
