The guy who thought of the "Take Your Top Off" slogan was probably real proud of himself. Of course, he owes a debt of gratitude to the grandaddy of all automobile advertising innuendo - the infamous Plymouth Star Chief "Spread Your Legs" campaign...
And who could forget this successful slogan from 1975?
The original ad read "Gimme Some Trim, Dammit! I Gots To Have Me Some Mother F***ing Trim!" but was shortened. Marketing experts wisely determined that a more abbreviated catch phrase was more direct and easily remembered.
(The top ad is from a 1979 issue of Orange Coast magazine. The bottom two are by yours truly.)
