A man walks up to a woman in his office each day, stands very close to her, draws in a large breath of air and tells her that her hair smells nice.
After a week of this she can't stand it any longer! The woman goes into her supervisor1's office and tells him that she wants to file a sexual harassment2 suit against the man and explains why.
The supervisor is puzzled by this and says, "What's wrong with the co-worker telling you your hair smells nice?"
