Simpsons Season 9, Episode 12: Bart Carny

While the family is at a traveling carnival, Bart accidentally crashes Adolf Hitler's car. To pay off the debts, Homer and Bart get jobs at the carnival by helping with the booths and exhibits, where they befriend Cooder and Spud, a father-and-son carny team. Unfortunately, Homer causes their booth to get shut down, when he does not recognize the bribe Chief Wiggum was asking for.
