Hal: You cannot be pregnant. We're not ready for this.
Lois: When have we ever been ready for this, Hal?
[flashback to Lois groaning on the floor of the church as she's pregnant with Francis:]
Lois: Okay, go ahead.
Priest: The blessed state of matrimony is a sacred place...
Lois: [screams] Oh, God!
Hal: Maybe we should get you to the hospital.
Lois: No! I will not have our baby born out of wedlock!
Hal: I don't understand why all of a sudden you're so hung up on this. Up until last week a marriage certificate was just a piece of paper.
Lois: [grabs Hal] I changed my mind!
Hal: And it made me the happiest man in the world.
