I was thinking of the old time advertising jingles that we heard growing up. To be correct, a jingle is set to music. But for our purposes today, I use the word "jingle" to describe any advertising catchphrase. I had to google this because my memory wasn't so good, but here are a few examples from my childhood:
"Hungryyyyy, Hungry Jack. They gobble 'em up and the plate come back for Hungry Jack."
"All - tempa - Cheer"
"Please don't squeeze the Charmin!"
"I can't believe I ate the whole thing"
"Where's the beef?"
"Look Ma, no cavities!"
"Plop plop Fizz fizz O what a relief it is" "I can't believe I ate the WHOLE thing
