The Gene Autry Show (1950) : 5x12

Pat enters a chariot race at a local fair that's in town. Confident that Pat will win, Gene places a bet, using the budget of an old school that's funding for a new building. There's dirty playing as the champion chariotist sabatoges Pat's chariot. This doesn't go unnoticed by Gene, and insists that Pat trade chariots. Pat wins the race, and the school is on it's way to having a new building.
