The episode: “Master Ninja I,” ep. 322
The riff: Sung by Tom as Timothy van Patten attempts to drive and a ninja blows out his tires with a throwing star.
The explanation: Tom is singing in parody of Texaco, the national oil and gasoline station chain. Throughout the 1970s they ran ads touting the chain’s reliability, saying “You can trust your car, to the man who wears the star.”
Novelty factor: I had no idea of this old slogan, but it’s a pretty clever riff now that I understand it. I also had no idea how over-the-top these Texaco ads were, this is like a Superbowl ad or something.
