Ravilious: Tests are being distributed. Keep them face down, please, because I'm going to time you. I will be strict about talking -- you can ask the three kids in fourth period who lost their quiz papers. From now on, any talking is cheating.
Student: But they're face down.
Ravilious: Tests are out, and I will consider it cheating if you talk.
Student: But you can't cheat if they're face down.
Ravilious: (sighes) I'm glad that my students are so deeply intellectual.
