actually I was thinking of jingles, not just slogans - the kind of thing you can amaze your GK's with.
Here is another one, not advertising but I heard it on the radio and can still repeat it perfectly 40 years later.
One hen
Two ducks
Three squawking geese
Four limerick oysters
Five corpulent porpoises
Six pair of Don Alverzo's tweezers
Seven thousand Macedonians in full battle array
Eight brass monkeys from the ancient sacred crypts of Egypt
Nine apathetic, sympathetic, diabetic, old men on roller skates with a marked propensity towards procrastination and sloth
Ten lyrical, spherical diabolical denizens of the deep who hall stall around the corner of the quo of the quay of the quivery, all at the very same time.
Now, who can sing the entire "See the USA in your Chevrolet"? as sung by Dinah SHore in 1952?
