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 GP 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."
