Engineering Medicine

An engineer can�t find a job, so he opens a clinic and puts a sign outside that says, �Treatment--$50.  If not cured, get back $100.�

A doctor thinks this is a chance to show up the engineer and earn a quick $100, so he visits the clinic.  �I have lost my sense of taste,� the doctor says.

�Nurse,� the engineer says, �bring the medicine from box #22 and place three drops in the patient�s mouth.�

The doctor spits out the liquid and says, �This is not medicine.  It�s gasoline!�

�Congratulations,� the engineer says, �you have your taste back.  That will be $50,�

The doctor is really annoyed.  He returns after several days to recover his money.  �I�ve lost my memory,� he tells the engineer.  �I can�t remember a thing.�

�Nurse,� the engineer says, �bring the medicine from box #22 and place three drops in the patient�s mouth.�

�The medicine in box #22 is for the sense of taste,� the doctor protests.  �Besides, it�s gasoline, not medicine.�

�Congratulations,� the engineer says, �you have your memory back.  That will be $50,�

The doctor leaves, more determined than ever to defeat the engineer.  After several days, he angrily returns for one last try.

�I�m going blind,� the doctor says.  �I can barely tell light from darkness.�

�I don�t have any medicine for that,� the engineer says.  �Take this $100.�

�But this is a $50 note,� the doctor says.
