Lois: Francis, if it isn't right in the bedroom, it isn't going to be right anywhere else.
Francis: What?
Lois: When I say "the bedroom," I mean sex.
Francis: Yeah, I got it.
Lois: Francis, marriage isn't mental. It isn't even really about feelings. When you get right down to it, it's a sloppy, sweaty physical act. Now, your father may have flaws, he may not make a lot of money, but he has never been other than a rigorous and challenging lover.
Francis: Mom.
Lois: Can I be frank with you?
Francis: No!
Lois: Do you remember sometimes in the morning I'd forget to put juice in your lunchbox? I was lucky I could remember my own name.
Francis: Uh-huh.
Lois: Because, when your father gets down to work, and is intimate with me, he is like a skilled general invading a country. He doesn't just launch an assault by sea, he uses paratroopers and columns of infantry. And even secret agents. [Francis throws up] Honey, good for you. Get it all out. We can talk more later.
