Old rules An old farmer became very bored and decided to open a medical clinic. He put a sign up outside that said: “Get your treatment for US$500 — if not cured get back US$1,000.” Richard, who was positive that this old guy didn’t know beans about medicine, thought this would be a great opportunity to earn some money. Richard: “Doctor, I have lost all taste in my mouth. Can you help me?” Old farmer: “Nurse, please bring medicine from box 22 and put three drops in his mouth.” Richard: “This is gasoline!” Old farmer: “ You’ve got your taste back! That will be US$500.” Richard was annoyed and went back the next day. Richard: “I cannot remember anything now.” Old farmer: “Nurse, please bring medicine from box 22 and put three drops in the patient’s mouth.” Richard: “Oh no, that’s gasoline!” Old farmer: “ You’ve got your memory back! That will be US$500.” |
