An old Dr. Geezer became very bored in retirement and decided to open a clinic.
He put a sign up outside that said: "Dr. Geezer's clinic. Specialist treatment for £500. If not cured, you get back £1,000."
Doctor "Young," who was positive that this old Dr.Geezer didn't know beans about modern medicine, thought this would
be a great opportunity to make a quick £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!! -- That's Petrol!"
Dr. Geezer: "Congratulations! You've got your taste back. That will be £500."
Dr. Young is annoyed and returns 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's Petrol"
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“ he complains.
Dr. Geezer: "Well, I don't have any medicine for that so, here's your £1000 back." (giving him a £10 note).
Dr. Young: "But this is only £10!"
Dr. Geezer: "Congratulations! You got your vision back! That will be £500.
