He opens a clinic and puts a sign outside.
‘GET TREATMENT FOR $20 – IF NOT CURED GET BACK $100.’ A lawyer thinks this is a great opportunity to earn $100 and goes to the clinic.
Lawyer: “I have lost my sense of taste.”
Doc; “Nurse, bring medicine from box No. 22 and put 3 drops in patient’s mouth.”
Lawyer: “Ugh. this is kerosene.”
Doc; “Splendid, 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.”
Doc; “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.”
Doc; “Awesome, 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.”
Doc; “oh well, I don’t have any medicine for that, so take this $100.”
Lawyer (staring at the note): “But this is $20, not $100!!”
Doc; “Spectacular, your eyesight is restored. Now you owe me $20”
