An engineer who was unemployed for a long time decided to open a medical clinic. He puts a sign outside the clinic: "A CURE FOR YOUR AILMENT GUARANTEED AT $500.00; OR WE'LL PAY YOU $1000.00 IF WE FAIL."
A doctor thinks this is a good opportunity to earn $1000.00 and goes to this clinic.
DOCTOR: " I lost my sense of taste."
ENGINEER: "Nurse, please bring the medicine from box 22 and put 3 drops on the patient's mouth."
DOCTOR: "That stuff is gasoline!"
ENGINEER: " Congratulations! You've got your taste back.
That will be $500.00."
The Doctor gets annoyed and goes back after a couple of days later to recover his lost money.
DOCTOR: " I have lost my memory, I cannot remember anything."
ENGINEER: " Nurse, please bring the medicine from box 22 and put 3 drops on the patient's mouth."
DOCTOR: "But, box 22 is gasoline!!"
ENGINEER: " Congratulations! You've got your memory back.
That will be $500.00."
The Doctor leaves angrily and comes back after several days, more determined than ever to make his money back.
DOCTOR: " My eyesight has become weak."
ENGINEER: Well, I don't have any medicine for this problem. Here take this $1000.00 bill, passing the doctor a $500.00 bill.
DOCTOR: "Wait a minute this is only a $500.00..."
ENGINEER: "Congratulations! You've got your vision back!
That will be $500.00"
