Dewey: I'm all packed up.
Hal: Good for you. Are you going somewhere?
Lois: He's going to Francis's. Let's go over the rules again. When you are on a bus, what are you to do?
Dewey: Talk to no one, don't let anyone sit next to me, try to look sickly and learning-impaired, cough every few minutes and nose-picking's okay.
Lois: Encouraged. And what if you are on the bus for a few hours and you have to go to the bathroom really, really bad?
Dewey: I still don't go.
Lois: That's my boy.
