In this episode, Marge decides to leave her hair in its natural gray color while Homer helps find women to be with Moe.
Seeing a grey-haired couple having a good time unworried about their hair, Marge surprises both her family and the neighborhood by going completely gray and sporting a brand new mature hairdo.
Unhappy about Marge's look, Homer initially tells her she is his "silver belle" to appease her but subsequently spends more time helping Moe with women in order to avoid looking at her, during which he becomes increasingly popular with the young ladies.
At the club, she confronts him upon seeing a crowd of women flirting with him but Homer helps Marge realize that he only has eyes for her and proves that love is still in the Springfield air.
