Marge: Lisa needs to go to the museum tomorrow,
and I think you should take her.
Homer: Museum? Tomorrow? Oh, oh, Marge, I'd love to, but I was
planning on... [thinks to himself] Sleeping? Eating a big
sandwich? Watching TV? Spending time with the boy! [speaks up]
Spending time with the boy! The boy needs attention, Marge.
Marge: Homer, I've been talking to Lisa, and I'm concerned about your
relationship with her.
Bart: Me too, Mom. I think you're drifting apart.
Homer: Shut up, boy.
Marge: Homer, please.
Homer: Marge, you don't understand. I can't do it because...
[thinking to himself] You're trapped. If you were smarter, you
might think of something. But you're not, so you just might as
well... [speaks up] All right, all right, I'll take her.
[sotto voce] Lousy brain.
