The episode: “Johnny at the Fair,” the short preceding “The Rebel Set,” ep. 419
The riff: Delivered by Joel in his little kid falsetto voice as young Johnny runs about and the camera shows a quick shot of his feet.
The explanation: Red Goose Shoes were apparently a popular old-time shoe brand, making red leather shoes like these. The brand’s motto was “Half the fun of having feet is Red Goose Shoes.” They were apparently a bit gimmicky as a brand, and shoe stores would be outfitted with a “red goose box” of sorts that could lay a “golden egg” with prizes for kids if the parents bought a pair of the shoes. These eggs would contain candy or a small toy.
Novelty factor: I had absolutely no idea, of course. It was difficult even finding an adequate description of what Red Goose Shoes were for this one. This may be the most obscure reference we’ve had on the blog so far.
