... which reminds me of the story ...

of the Professor who was irritated by a student who continued to write in his blue book after the Prof had announced the end of the exam period. The student finally finished what he was writing and took it to the front of the classroom, where the Prof had all the other blue books piled on the table. The Prof said that he would not accept the blue book because it had been turned in late. The student huffed, and asked, "Don't you know who I am?" The Prof replied, "I don't know and I don't care who you are." And the student quickly scattered the pile of blue books, inserted his into the mess, and ran out of the room.
