Here I go again

A group of students are taking an exam and a Professor says that the time is up and every student must hand in their papers immediately or they will receive a zero. All students but one hand in their assignments. Half an hour later the final student approached the Professor. The Prof says "You know I'm going to fail you for this." The student replied "Do you have any idea who I am?" "No." The student puts the exam in the middle of the stacked pile of exams and scatters it on the floor.

Two girls are roommates at a college dorm. One of them is very sexually active and the other tries to ignore it in her sleep. The room is shared, the beds are in the same room, only the darkness keeps the privacy. So one night the young lady comes home from a party drunk and in her room she hears noises again. She doesn't bother doing anything since she is drunk and goes straight to sleep with her clothes on. The next morning she wakes up and finds her roommate was murdered, and on the wall there was text in blood "Aren't you glad you didn't turn the light on?" Since her roommate died, she aced all of her classes.
