We've all heard them.  They make the advertising world go round. Those jingles or slogans that will stick in your head forever. There have been some really catchy ones over the decades.

One that comes to mind is the Alka Seltzer jingle that played on TV and radio. "Plop, Plop, Fizz, Fizz, Oh What a Relief It Is".  I can still picture the extremely hungover guy in the TV commercial. Or, who remembers the McDonald's catchy jingle "Two All Beef Patties, Special Sauce, Lettuce, Cheese, Pickles, Onions on a Sesame Seed Bun". That one is from 40 plus years ago and I still remember it, word for word. That is great advertising.

Advertisers really know how to mess with your mind. There was a chain of grocery stores in my hometown that for years used the same jingle. Then one day they dropped the words and just played the instrumental. I would hear the music and start singing the words in my head. Brilliant!

Name a slogan or jingle that sticks in your head.
