That jingle burrowed in deeper than family. My grandma could hum the whole "plop plop fizz fizz" thing but drew a blank on my middle name every single time. Ads back then were built to stick in your brain like glue, catchy tunes and weird mascots you couldn't shake. Family stuff just didn't get the same repeat plays. Crazy how a 30 second spot from 1976 outlasts real memories.
