Ralph hocks his bowling ball to get Alice a present when someone else gets her the same thing he did.

Ralph's lodge brother, Stanley, is about to marry Alice's sister, Agnes. At the Raccoons' bachelor party for Stanley, Ralph warns the young man not to move in with Agnes's parents after the wedding. But this advice backfires when Agnes shows up at the Kramdens' after the wedding reception, sobbing that her new husband has changed into a "beast". Can Ralph get Stanley and Agnes back together without Alice knowing that he was the one who gave Stanley the advice?

A new neighbor moves next door to the Kramdens. This neighbor is a dance instructor and teaches the wives to do the mambo, at their husbands' collective expense.
