A Chinese doctor can't find a job in a Hospital in the US, so he opens his own clinic and puts up a sign outside. It reads: 'GET TREATMENT FOR $20 - IF NOT CURED GET BACK $100.' An American lawyer thinks this is a great opportunity to earn $100 and goes to the clinic. Lawyer: 'I have lost my sense of taste.' Doctor: 'Nurse, bring medicine from box No. 22 and put 3 drops in patient's mouth.' Lawyer: 'Ugh, this is kerosene!' Doctor: 'Congrats, your sense of taste is restored. Give me $20.' The annoyed lawyer goes back after a few days to recover his money. Lawyer: 'I have lost my memory. I cannot remember anything.' Doctor: 'Nurse, bring medicine from box no. 22 and put 3 drops in his mouth.' Lawyer (annoyed): 'This is kerosene. You gave this to me last time for restoring my taste.' Doctor: 'Congrats. You got your memory back. Give me $20.' The fuming lawyer pays him and then comes back a week later determined to get back $100. Lawyer: 'My eyesight has become very weak I can't see at all.' Doctor: 'Well, I don't have any medicine for that, so take this $100.' Lawyer (staring at the note): 'But this is $20, not $100!!' Doctor: 'Congrats, your eyesight is restored. Give me $20.'
