The legendary adman? David Ogilvy, was a young copywriter when he wrote this slogan in a moment of sheer inspiration and creativity as he was listening to the client brief him. Of course it was never used. But it captures the essence of the Unique Selling Proposition (USP) and tells it in a memorable and simple way. Hers is the original Ogilvy version:
Carnation milk is the best in the land,
Here I sit with a can in my hand,
No tits to pull or hay to pitch,
Just punch a hole in the son-of-a-bitch!
