A professor gave a test to his class of three hundred, and gave one hour to have it done.
At the end of the one hour, there was one student who was still scribbling furiously.
The professor watched in amazement as everyone left, and still the student kept writing. 15 minutes later, the student boldly walked up to the professor with his now completed Final Exam.
The professor said, "You don't imagine I'm going to accept this, do you?" To which the student looked him haughtily in the eye and said, "Do you know who I am?"
The professor, puzzled, said, "No.", at which point the student shoved his exam in the middle of the pile and said, "Good", and walked out.
