Kaye's grandmother comes from Italy for the kids' wedding, and since nobody has the heart to tell her it was a year ago, a formal wedding is staged, with Suzie finding out in mid-ceremony that she's pregnant.

Eve and Kaye team up to write a TV script, and wind up begging Roger for ideas, snapping at each other, and trying to retrieve their script, which they plagiarized, after Roger submits to it for them.

When the men cancel their wives' charge accounts, the mothers decide to overcome their forced recession by getting jobs as department store saleswomen.

Eve and Kaye resort to domestic spying when they become jealous of the gorgeous new secretary their husbands hired to work at home: Kaye bugs Roger's den and Eve listens to Herb's sleep-talking.

On the sly, the in-laws slip $40 into Jerry's old jacket for the couple's anniversary celebration. Unaware, Suzie donates the coat to a thrift shop, sending the mothers on a spree to retrieve it.

The mothers arrange for the debut of Jerry's nightclub act, which features a Jimmy Durante impersonation, but when he comes down with the flu, the Hubbards and Buells take his place. Jimmy Durante makes a cameo appearance.

Going to a store to return a duplicate wedding gift for the kids, the mothers, who have been banned from their own phones for continually calling the honeymooning couple, spend $15.70 talking to them on a payphone, unknowingly getting locked in the store when it closes. With only one dime left, they accidentally reach a sleeping bullfighter in Barcelona, whom they beg to relay their SOS to their husbands. Madness ensues when a security guards finds...

Eve and Kaye turn Herb’s office into a model of inefficiency when they take over for his sick secretary.

The Hubbards and the Buells battle as they both want, and then don’t want, the boat they won on a telephone quiz show.
