Quentin and Calvin Klein
Quentin spear-headed Calvin Klein's add campaign in America for his unisex CK1 perfume.
For one commercial he had to travel to Brooklyn. When he got there he found a square of paper and six very thin people standing on it, and a man naked to the waist crawling on the floor between their feet.
Quentin looked at Calvin and asked
"What does it all mean?"
Calvin replied
"Say that again".
Quentin found he had just written the dialogue for the commercial.
