Consider this billboard advertisement in New York:

Why would a company deliberately advertise its products by illustrating a perverted sexual romp (possibly involving minors) and then put it on a billboard so large that the body parts are the size of automobiles? Is this suppose to encourage us to buy their jeans?
It certainly is thoughtful of the Calvin Klein company to help make up my mind never to buy any of their products. I'd say their advertising campaign is a smashing success.
