AL      We don't need a computer, and I'll tell you what would happen if we got one: just like when we had the kids, everybody "ooh"s and "aah"s the first couple of days, then after the novelty wears off, it just sits there, collects dust and cries for food. No, I'm telling you, nobody needs kids. [catches his mistake] No, I mean - I mean a computer.

PEGGY   Oh, Al. Just because we're flat broke, doesn't mean we have to live like animals. Now, this machine is gonna wind up saving us money in the long run.

AL      How? Does it emit powerful, life-draining radiation?

PEGGY   Well, I don't know. I don't even know how to use it. I don't even know why we need it, I just know I want it. You know, like when we had the kids.
