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:

Marge:

Homer:
I'm with you, Marge. Lisa, get in here.

[Lisa walks in]

Homer:
In this house, we obey the laws of thermodynamics!
