Tuning Fork, Mississippi is a small village with a population of 10, which George visits in a fantasy in "Big Horns George".
George has the fantasy while listening to Taj Mahal's music. He and Wally have lemonade at the General Store, but since they can not pay for their drinks, the sheriff (Binky) gives them until sundown to raise the money by singing.
George sings quietly, which causes a lady (Francine) to remark that he sounds like a mouse. A blues singer (Taj Mahal) tells George that a mouse has feelings and he should put more feeling into his singing. George is a much better singer after that.
Tuning Fork resembles the town where Grandpa Dave lives. The truck driver who Takes George there is a lookalike of Ed Billings.
