A blonde and a brunette boarded an elevator.
On the next floor, the door opened and a man wearing a black suit got on the elevator.
It was pretty evident by the white flakes speckling his suit that the man had a pretty bad dandruff problem.
Two floors later the man got off, and the two women remained.
After the door closed the brunette said, “Someone should give that guy some Head & Shoulders.”
The blonde thought about it for a moment before her head cocked itself to the side and she asked, “How do you give shoulders?”
