A professor stood before his class of 20 senior organic biology students,
about to hand out the final exam.
"I want to say that it's been a pleasure teaching you this semester. I know
you've all worked extremely hard and many of you are off to medical school
after summer. So that no one gets their GPA messed up because they might
have been celebrating a bit too much this week, anyone who would like to opt
out of the final exam today will receive a 'B' for the course."
There was much rejoicing amongst the class as students got up, passed by the
professor to thank him and sign out on his offer. As the last taker left
the room, the professor looked out over the handful of remaining students
and asked, "Any one else? This is your last chance." One final student
rose up and took the offer.
The professor closed the door and took attendance of those students
remaining. "I'm glad to see you believe in yourself." he said. "You
all have 'A's."
