An old geezer and Etch-a-sketch

An old geezer became very bored in retirement and decided to open a medical clinic. He put up a sign outside that said: "Dr. Geezer's Clinic. Get your treatment for $500, and 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.
Dr. Young: "Dr. Geezer, I’ve 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’ve lost my memory, I can’t 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’s 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".
Remember: Don't make old people mad. We don't like being old in the first place, so it doesn't take much to tick us off.
ENJOY YOUR DAY!!
