(Strip Number 915, Original Publication Date, 10 August 1985)
Panel 1: As they continue their conversation, Jean tells John that she never realized how much having a child would change her life.
Panel 2: Since she's the creation of an idiot who still thinks that a child is a doll she can put away when she's bored, we're supposed to sympathize with her when she's surprised that her entire day rotates around the schedule of a defenseless child.
Panel 3: Since she's also the creation of someone who rants about unfairness, she talks about how she has to get up every three hours to feed Brittany while her straw-man entitled chauvinist husband snores away.
Panel 4: Since John's the creation of someone who doesn't understand men, he thought-bubbles about how that's a great argument for breast-feeding.
Summary: I'd originally been baffled by this until I realized that since John doesn't have functioning breasts, breast-feeding means that he, the man, sleeps like he, the man, is supposed to because he, the man, deserves to be gut-shot for being a selfish piece of horse-droppings.
