Nagurski: Da-da, Tupolev's grampa was shot down.
Nagurski: In my class.
Da-da: Is his grampa ok?
Nagurski: Yeah. It was a long time ago.
Da-da: What kind of plane was it?
Nagurski: His jet was shot down during the Civil War.
Da-da: Oh. That kind of plane. Was he a Blue or Gray pilot?
Nagurski: [thinks] What does civil mean?
Da-da: It means, "polite," among other things.
Nagurski: So, it was a... polite war?
Da-da: Very. They interrupted battle to serve tea and little sandwiches every afternoon.
Nagurski: You're making this up.
Da-da: Am I?
Nagurski: Ye-es. [thinks] Hm. So, was Chewbacca on the Blue or the Gray side?
Da-da: That's a very good question.
