Do you know who I am?

One day a student was taking a very difficult essay exam. At the end of the test, the prof asked all the students to put their pencils down and immediately hand in their tests. The young man kept writing furioulsy, although he was warned that if he did not stop immediately he would be disqualified. He ignored the warning, finished the test 10 
minutes later, and went to hand the test to his instructor. The instructor told him he would not take the test.
The student asked, "Do you know who I am?"


The prof said, "No and I don't care."


The student asked again, "Are you sure you don't know who I am?" 


The prof again said no. So the student walked over to the pile of tests, placed his in 
the middle, then threw the papers in the air.


"Good" the student said, and walked out. He passed.
