Your teacher has assigned several homework assignments whose due-dates are spaced out over the course of the semester. You don't bother to do any of them. The
night before the final, you realize what a mistake that was, and you hurriedly do all of the homework assignments in succession. On entering the final exam, you
plop the lot of them on the teacher's
desk, unceremoniously and without explanation. This hail-Mary
hand-in subsequently becomes an object of incredulity and amusement among your teacher's colleagues.
