Groan!

[LesStrat]

An old geezer became very bored in retirement 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.

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"*

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.
