A woman went to her doctor for a follow-up visit after the doctor
 had prescribed testosterone (a male hormone) for her. 
 
 She was a little worried about some of the side effects she was
 experiencing. 
 
 "Doctor, the hormones you've been giving me have really helped,
 but I'm afraid that you're giving me too much. I've started
 growing hair in places that I've never grown hair before." 
 
 The doctor reassured her. "A little hair growth is a perfectly
 normal side effect of testosterone. Just where has this hair
 appeared?" 
 
 "On my balls."
