    It was the final examination for physics at the college. The examination was two hours long, and exam papers

were given. The professor (教授) was very strict and told the class that any exam paper which was not on his

desk in two hours would be refused and the student would fail. A half hour into the exam, a student came

rushing in and asked the professor for an exam paper.

    "You're not going to have time to finish this," the professor said slowly as he gave the student a paper.

    "Yes, I will," answered the student. He then took a seat and began writing. After two hours, the professor

began to call for the exam papers, and the students stood up and put them on the professor's desk, all except the

late student, who continued writing. A half hour later, the last student came up to the professor who was sitting

at his desk and busy writing something. He tried to put his exam paper on the stack (摞) of the other papers

already there.

    "No, you can't, I'm not going to take that in. It's late."

    The student became worried. He thought for a while, then he asked the professor in a low voice, "Do you

know WHO I am?"

    "No, surely I don't," answered the professor.

    "DO YOU KNOW WHO I AM?" The student asked again.

    "No, and I don't care," said the professor in a louder voice.

    "Good," answered the student, who quickly lifted the stack of exam papers, put his paper in the middle, and

rushed out of the room.
