A Chinese Doctor can't find a job in a Hospital in the US, so he opens his own Clinic and puts a sign outside ;-
'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.'
Chinese: 'Nurse, bring medicine from box No. 22 and put 3 drops in patient's mouth.'
Lawyer: 'Ugh. this is Kerosene.'
Chinese: 'Congrats, your sense of Taste is restored. Give me $20 dolla.'
The annoyed Lawyer goes back after a few days to recover his money.
Lawyer: 'I have lost my Memory. I cannot remember anything.'
Chinese: '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.'
Chinese: 'Congrats. You got your memory back. Give me $20 dolla.'
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.'
Chinese: 'Well, I don't have any medicine for that, so take this $100 dolla.'
Lawyer (staring at the note): 'But this is $20, not $100"...
Chinese: 'Congrats muddafucka, your Eyesight is restored. Give me another $20 dolla'
