If you thought someone saw “Piggly Wiggly” and thought “hmm, there’s an idea I could copy,” indeed:

The Hinky Dinky grocery store chain was started by Jule, Henry and Albert Newman, brothers, and Ben Silver, a cousin, in Omaha in 1925. Another supermarket chain already existing was called Piggly Wiggly. Hoping to take advantage of the public's affection for a cute name (Piggly Wiggly was very successful) they came up with "Hinky-Dinky", which was taken from the World War I song, “Hinky Dinky Parlez-vous” (see Mademoiselle from Armentières)
