My favorite monitor/proctor/invigilator story is of student taking exam in Mem Hall, in a room the size of a shopping mall, including a couple alcoves. In one of the latter a student did not realize exam time was over, until person in charge informed him he would not be allowed to submit his exam booklet. The student was quick wtted enough to rear back and demand: "Do you know who I am?" Startled, the official said:"No." "Good," said the student, and put his booklet into the pile of exam booklets, and tumbled them around.
