An Old Geezer

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 don't, -- 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 -- " Here's your $1000 back."
Dr. Young: "But this is only $500..." Dr. Geezer: "Congratulations! You got your vision back! That will be $500."
Moral of story -- Just because you're "Young" doesn't mean that you
can outsmart an old "Geezer " !!!!
