 In this episode, an orange Dodge Charger is a participant in the  race. The car is driven by a pair of relatives, one with blonde  hair, and one with dark hair. The pair have a Dixie flag on their  uniforms. Also, their vehicle is powered by moonshine. This seems  like a reference to the series The Dukes of Hazzard, where a pair of  cousins drive an orange Dodge Charger with a confederate flag  painted on the roof, and have a family history of driving moonshine  around a dry county.
