Head and Shoulders

A blond and a brunette are on an elevator, suddenly a good looking handsome man gets on. So then the brunette turns to the blond and says, "Wow, he is so good looking, but that dandruff on him is a real turn off."

"I think we should give him some Head and Shoulders!" said the brunette. All of a sudden the blond turned to the brunette with a confused look and said, "Ok, but how do you give shoulders?"
