My husband would look at the women in those nudie magazines and say, "How come you don't have any chest?" And I said to him, "When you married me, I didn't have a chest. But when I married you, you had a full head of hair."

The line is structured as a comic reversal: a husband’s crude comparison to pin-up models is met with a pointed reminder about changing bodies over time. Costello’s retort reframes the insult as a matter of fairness and expectation—she did not “change the terms” of the relationship, while he did (hair loss standing in for aging and physical change). The humor comes from the blunt specificity and the swift pivot from sexualized critique to an everyday, socially recognizable insecurity. Beneath the joke is a critique of double standards in heterosexual marriage: women are often pressured to match idealized images, while men’s aging is treated as normal or excusable.
