The Mothers-in-Law

The bickering Hubbards and Buells are stunned when their kids return from a night out announcing they're engaged. After arguments about the wedding plans are finally settled (amid the kids breaking up over a fight about whose mother is right), the kids wind up eloping with another couple, while their parents are trying to rescue Kaye's beloved grand piano, set up in the Hubbards backyard for the next morning's nuptials, from a midnight rainstorm.

The Hubbards and the Buells show up at the same resort, and when their honeymooning kids unexpectedly arrive, having been rained out at their original destination, the in-laws spend a sleepless night together in a cramped room, giving the only other available room to the kids. Desi Arnaz, Jr. can be seen in a golf cart in the opening scene.

Eve and Kaye break their legs skiing and are bedridden in the same room.

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 them trying on fur coats.

Checking out the place that the kids have rented, the mothers return their deposit and fix up the Hubbards garage apartment for them. After their snooping gets them caught hiding in the kid's shower, they promise not to interfere, but their curiosity gets to them when they see friends arriving for a dinner party. Peeking in the electric garage door windows, they wind up spending the evening lying atop the horizontal door after Jerry opens it for some fresh air.

To cut down on their wives meddling, Herb and Roger suggest that they get jobs. Realizing that all their suggesting, recommending, and advising might just be too much, they decide to try it. With Kaye's past signing career as Angelina Davina, The Little Girl with the Big Voice and Eve's youthful experience in local radio, they go to an audition for a revue at the hip Club Cabaret and work up a novelty act, calling themselves The Marvys. (Desi Arnaz, Jr. is seen playing the drums).
