There was a guy who was working as a teaching assistant for a large lecture
 class of about 100 undergraduates.  During the final exam he noticed one
 student cheating.  He brought the student to the attention of the other TA's
 and the professor, and they all agreed that the student was in fact cheating.
 
 At the end of the exam, the student brought his exam and tried to hand it to
 the TA.  The TA said, "I'm sorry.  I can't accept this.  We saw you cheating."
 The student looked at the TA and said indignantly, "Do you know who I am?"
 The TA said no.  The student looked to the other TA's and professor and
 indignantly asked them, "Don't you know who I am?"  They all said no.
 "Great!" he said, as he lifted up the stack of exams, shoved his in the middle
 and ran from the room.
