Free Advice

At a cocktail party, the lawyer was getting annoyed at the number of people who kept asking for free advice.  He asked his doctor friend if he had the same problem.

   "All the time," agreed the doctor.
   "Well, don't you get tired of it?  What do you do?"
   "It's very simple, and I think it will work for you," said the doctor. "When they ask for advice, just tell them to undress!"
