A blonde and a brunette both board an elevator and push the buttons for their respective floors. On the next floor, the door opens and a businessman wearing a black suit boards the elevator. It’s evident that the man has dandruff problems, because it can be seen on the shoulder of his suit.

Two floors later the man gets off, and the two women remain. When the door closes the brunette says, “Someone should give that guy some Head & Shoulders.”

The blonde then responds, “How do you give shoulders?”
