(Sheldon is leaving a classroom after the teacher sneezes two times)

Ms. MacElroy: Where do you think you're going?

Sheldon Cooper: Away from you.

Ms. MacElroy: Why's that?

Sheldon Cooper: I want to live.

Ms. MacElroy: I'm not sick. Get back in your seat.

Sheldon Cooper: No, thank you.

Ms. MacElroy: You know the rules. You can't leave without a hall pass.

Sheldon Cooper: May I have a hall pass?

Ms. MacElroy: No, you may not. Now get back in your seat.

Sheldon Cooper (narration): Rules are the pillars of society. I love rules. But what benefit are rules to a dead man?
