A recent grad student can't find a job so 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.
Student: Nurse, bring medicine from box no. 22 and put 3 drops in patient's mouth.
Lawyer: Ugh..this is kerosene.
Student: Congrats, your sense of taste is restored. That'll be $20.
The annoyed lawyer goes back after a few days to recover his money...
Lawyer: I have lost my memory. I cannot remember anything.
Student: 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.
Student: Congrats! You got your memory back. That'll be $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.
Student: Well, I don't have any medicine for that, so take this $100.
Lawyer: *staring at the note* But this is $20, not $100!
Student: Congrats, your eyesight is restored! $20, please.
