I remember this one from Philosophy in college. Student: *Not taking notes* Teacher: Why aren't you taking notes? These are the exact questions that will be on the test. Student: I dunno. Teacher: Let me ask you, if you had a friend; who was taking a class where he would get an A easily if he just took notes, yet refused to take notes, what would you say to him? Student: He's an idiot. Student: *continues to not take notes* Teacher: My point proven.
