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 supervisor's office, tells him what the coworker does, and that she wants to file a sexual harassment suit against the man.
The supervisor is puzzled by this and asks, "What's sexually threatening about a coworker telling you your hair smells nice?"
The woman replies, "He's a midget!"
