A Chinese doctor can’t find a job in an American hospital, so, he opens a clinic and puts a sign outside that 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 drawer # 14 and put 3 drops in patient’s mouth.”

Lawyer: “Ugh. This is gasoline!”

Doctor: “Congrats, your sense of taste is restored. Give me my $20.”

The annoyed lawyer goes back after a few days to try to recover his money.

Lawyer: “I have lost my memory. I can’t remember anything.”

Doctor: “Nurse, bring medicine from drawer # 14 and put 3 drops in his mouth.”

Lawyer (annoyed): “This is gasoline. You gave this to me last time to restore my taste.”

Doctor: “Congrats. You got your memory back. Give me $20.”

The fuming lawyer pays him, then comes back a week later determined to get back $100.

Lawyer: “My eyesight has become very poor; I cannot see at all.”

Doctor: “Well, I don’t have any medicine for that, so take this $100.”

Then the Doctor hands him a $20 bill.

Lawyer (staring at the money): “But this is $20, not $100!”

Doctor: “Congrats, your eyesight is restored. Give me $20”
