Oliver takes Arnold the Pig Chicago to receive Arnold's inheritance of $20,000,000. Arnold is a direct discendant of Herman, a pig who could predict the weather with his tail. However, Oliver soon finds it difficult watching after a pig in the hotel.

Oliver's angry over Hooterville's dirt road, especially after learning the money to pave it was appropriated thirty years earlier. Never content to leave well enough alone, he descends on the state capitol demanding that something be done. He makes little headway until Lisa mentions the name of powerful hot dog vendor Big Joe Haney.
