A blonde and a brunette are both in an elevator.
On the third floor a man gets on who's perfect: Italian suit, handsome, great build with a nice butt, but unfortunately they both notice he has a bad case of dandruff. The man gets off on the 5th floor.

Once the doors close, the brunette turns to the blonde and says, "Someone should give him Head & Shoulders."

To which the blonde replies, "How do you give Shoulders?"
