Wisdom Humor - doctor cures with money-back guarantee

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."

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 !!!!

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."
