A retired physician, Doctor Gordon Geezer, became

A retired physician, Doctor Gordon Geezer, became very bored in retirement and decided to re-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 Digger 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.
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."
Dr. 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 anything!"
Dr. Geezer:
"Well, I don't have any medicine for that so, "Here's your $1000 back"
(giving him a $10 bill).
Dr. Young:
"But this is only $10!"
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"
