The Doctor and the Rich Man An immigrant doctor decided to start his own clinic one day. He put a sign in front of it that says if he can't cure your illness, he'll give you 100 dollars. If he can, you have to pay 20 dollars. A young rich man passes by, sees the sign, and thinks it's a good opportunity to earn 100 bucks. Then, he enters the clinic. The doctor asks the man what he is feeling. “I lost my sense of taste.”  says the rich man. The doctor then calls a nurse, and asks her to get the medicine from box 25 and put 3 drops in the patient's mouth. The nurse drops 3 drops of medicine into the rich man's mouth. Then he exclaims, "Is that urine!?" "Congratulations! You have been cured of your disease. Now, please, my 20 dollars." says the doctor. The rich man reluctantly gives the money. After a few days, the infuriated man returns to the clinic, trying to get his money back. "I lost my memory, I cannot remember anything!" the man retorts. The doctor then calls a nurse, and asks her to get the medicine from box 25 and put 3 drops in the patient's mouth. "Again?! Isn't that urine?" the wealth man responds. "Congratulations! You have been cured of your amnesia. Now, please, my 20 dollars." says the doctor. The man, already fuming, pays the clinician. He returns a week later, determined to win the cash. "My vision is very weak, and I can't see anything."  "Well, I don't have any medicine for that, so take $100." the doctor responds. "But this is a 20 dollar bill!" says the man, outraged. "Congratulations! You have been cured of your blindness. Now, please, my 20 dollars."
