Marge: So in a few months, both of you will have a brand new brother or
sister.
Bart: Been there, done that.
Lisa: I hope it's a girl.
Bart: You know nothing about genetics, Lis: it goes boy, girl, boy,
girl.
Lisa: You're worried about telling Dad, aren't you, Mom?
Marge: Why do you say that?
Lisa: Well you've been in my room for about four hours now.
Marge: Hey, I'm just hangin'.
