Outsmarting the Doctor....
 
An old geezer, who had been a retired farmer for a long time, became very bored and decided to open a medical clinic.

He put a sign up outside that said: Dr. Geezer's clinic.  Get your treatment for $500, if not cured get back $1,000."
Doctor Young, who was positive that this old geezer didn't know beans about medicine, thought this would be a great opportunity to get $1,000. So he went to Dr. Geezer's clinic.

This is what transpired.
Dr. Young: --- "Dr. Geezer, I have lost all taste in my mouth." can you please help me?
 Dr. Geezer:  ---   "Nurse, please bring medicine from box 22 and put 3 drops in Dr. Young's mouth."
 Dr. Young: --- Aaagh !! -- "This is Gasoline!"
 Dr. Geezer: "Congratulations! You've got your taste back. That will be $500." Dr. Young gets annoyed and goes back after a couple of days figuring to recover his money.
 Dr Young: "I have lost my memory, I cannot remember anything."
Dr. Geezer: "Nurse, please bring medicine from box 22 and put 3 drops in the patient's mouth."
Doctor Young:  "Oh no you dont, -- that is Gasoline!"
Dr. Geezer: "Congratulations! You've got your memory back. That will be $500."
Dr. Young (after having lost $1000) leaves angrily and comes back after several more days.
Dr. Young: "My eyesight has become weak --- I can hardly see !!!!
Dr. Geezer: "Well, I don't have any medicine for that so -- Heres your $1000 back."
Dr. Young: "But this is only $500..."
Dr. Geezer: "Congratulations! You got your vision back! That will be $500."
Moral of the story --   Just because you're Young doesn't mean that you can outsmart an old  Geezer!!!!
