A young woman visited her doctor complaining of a bed wetting problem.
   The doctor asked her the usual questions and then asked her to go
   behind the screen and remove her clothes. She was a bit shocked but
   went ahead anyway.
   
   When she was undressed he asked her to stand on her hands in front of
   and facing a full length mirror. The young woman was even more shocked
   but if it would help solve her problem she thought she had better do
   what the doctor said.
   
   As soon as she was in position the doctor asked her to open her legs
   and when she did he put his head between them and rested his chin
   right on her private parts. After a few moments and some very positive
   'yes, yes' type noises the doctor instructed her to get dressed again.
   
   Afterwards, the doctor sat her down and informed her that the main
   cause of her problem was just that she was drinking far too much
   liquid before going to bed.
   
   "So what did the exercise in front of the mirror tell you?"
   
   "Well," said the doctor, "my wife is right, a beard would suit me."
