The Clampetts Strike Oil

Jed Clampett is told by a representative of an oil company that the swamp behind his shack is full of oil. (The oil company employee has been hauled in by Jed's daughter Elly May who asks whether she can keep him.) Later, Mr. Brewster, the head of the oil company, does a deal with Jed. Jed tells Cousin Pearl that he'll receive 25 to 100 of "some new kind of dollar." (imdb)
