Marge: I'm worried about the kids, Homie. Lisa's becoming very obsessive. This morning I caught her trying to dissect her own raincoat.
Homer: I know. And this perpetual-motion machine she made today is a joke. It just keeps going faster and faster.
Marge: And Bart isn't doing very well either. He needs boundaries and structure. There's something about flying a kite at night that's so unwholesome.
Bart: Hello, mother dear.
Marge: That's it, we have to get them back to school.
Homer: I'm with you, Marge. Lisa, get in here.
Homer: In this house, we obey the laws of thermodynamics!
