Prof: "Did you read philosophy?"
The Boy:"No"
Prof: "You are useless in the world"
Prof: "What about psychlogy?"
The Boy: "No"
Prof: "You are a waste"
Prof: "Did you read phamacology?
The Boy: "No"
Prof: "You are good for nothing"
After a while there was excessive wave and the canoe was shaking to capsize.
The boy quicky abandoned the prof to fate. The helpless prof was in great fear, yelling at the litte bot for help.The Boy asked him " Prof, have studied Swimmology?" Now you are the one finished.
