Now that they have Little Ricky, Lucy insists they need more room, and wants to change apartments with one of the other tenants (Mrs. Benson.) She convinces a reluctant Ricky by cluttering their apartment with baby things and assorted junk.

Lucy promised Carolyn Appleby she'd produce some real Hollywood celebrities. Now she's got to deliver. Dressing up as Clark Gable, Gary Cooper and other celebrities, she manages to fool the near-sighted Carolyn. However, the real Harpo Marx shows up only to discover Lucy dressed up as him.

Lucy is spotted while attempting to "collect" a cement block with John Wayne's footprints from Grauman's Chinese Theater. To avoid publicity and keep Lucy out of jail, Ricky enlists John Wayne's help in replacing the block. One mishap leads to another, and the plot thickens -- as does the cement. John Wayne guest-stars.

En route to Rome by train, Lucy is spotted by a famous Italian cinema director and chosen to play a part in his new movie "Bitter Grapes." Lucy sets out to immerse herself in the role. When she nonchalantly wanders into a vineyard inhabited by a motley assortment of Italian-speaking women, she is dispatched to the wine-making area to crush grapes with her feet.

Ricky is disgusted by Lucy's obsession with gossiping about other people. According to Ricky, Lucy acts as if it is her ""life's blood."" Fred, too, is disturbed by Ethel's love of gossiping. The two girls then point out that both Ricky and Fred have been known to gossip, also. The boys then challenge the girls to a bet: They will see who can go without gossiping the longest, and the winners will receive breakfast in bed for a month. The bet commences, and everything is going fine until Ricky comes up with a plan to cheat so that he and Fred can win.

Having been bet by their husbands that they can't do without modern conveniences, Lucy and Ethel churn butter and bake bread from scratch-an eighteen foot loaf! But then Lucy demands that Ricky live as if it's the turn of the century for him, too.

Where's the beef? It's in Lucy and Ethel's new walk-in freezer (according to Lucy, the "human popsicle"). Of course, Ricky and Fred have a beef with their wives, because they paid $483 for it. The meat company won't take it back, and they can't sell it to customers waiting in the local butcher shop, so they're stuck with it. And speaking of stuck, Lucy gets herself locked in the freezer!

Desperate to be in Ricky's new television commercial, Lucy makes every attempt to get her way; which eventually pays off. But her one-and-only chance flops when she is forced to test the sponsor's product over-and-over, a vitamin syrup called Vitametavegimin, which is 25% alcohol.

Ricky and the Mertzes bet Lucy that she can't go twenty-four hours without telling a lie. The outcome? Lucy insults all her friends and has to admit her real age, weight, and hair color. But she nearly gets a part on a TV show, by telling the truth, more or less.

Lucy spends too much money on a dress. So she tells Ricky that she will get a job babysitting in order to pay for it.

Championship golfer Jimmy Demaret visits the Ricardos when Lucy and Ethel arrive at a bizarre scheme for combating their "golf widowship." The girls install a basketball court in the Ricardo living room and pretend to be as deeply absorbed in the game as their husbands are in the fairways.

The Ricardo household budget is in shambles (as usual) after Lucy decides to put her salad dressing on the market. Her plan? To market it on a TV morning show on the station her friend Caroline Appleby's husband runs. Home economist Mary Margaret McMertz (Ethel) will invite "an average housewife," (Lucy) to taste the dressing on the air.

It's time for charm school for Lucy and Ethel when their men eye a pretty woman at a party. But Ricky and Fred are anything but charmed by the results.

Lucy and Ethel buy the same dress for the upcoming talent show for the Wednesday Afternoon Fine Arts League. True, they'll be doing a duet, and their number is Cole Porter's corny "Friendship" but wearing the same dress isn't exactly what they had in mind. Meanwhile, Lucy needs to persuade Ricky to host the show, so she decides to use a little reverse psychology.

Lucy and Ethel demand equal rights for women. Okay, say Ricky and Fred at the restaurant: separate checks for the four of them. Thus begins Lucy and Ethel's careers as restaurant dishwashers. So they plot revenge: they'll scare their husbands by claiming to have been robbed.

Lucy sneaks into the Mertzes' apartment to borrow one of Fred's suits so that she can order him a custom-made tweed suit for his birthday. This leads Ethel to think that Lucy is the notorious neighborhood burglar, "Madame X", and she goes spying on her friend to prove it.

Lucy and Ricky want to spend their 13th wedding anniversary alone, but the Mertzes have another idea: a surprise party.

Ricky explodes when Lucy buys an expensive hat. She offers to return it, and bets him he'll lose his cool over something else before she buys another hat. But no matter what she does to provoke him, the hot-tempered Cuban remains unruffled.

The Ricardos and the Mertzes buy a diner, name it "A Little Bit of Cuba" and go to work. Well, the Mertzes go to work; the Ricardos "greet." Not surprisingly, relations are soon strained. Can a food fight be far behind?

Ricky agrees to watch his son, but while Daddy is engrossed in a football game, Little Ricky wanders off. Lucy finds him in the hallway, and calls Ricky to ask where the baby is. Panicking, Ricky searches everywhere, before Lucy walks in with his son.

Ricky's home movies move the Mertzes to walk out, and prompt Lucy, Fred and Ethel to make a movie of their own, a "Western musical drama" shot in the Ricardo living room. But that's not to mixed up with a TV pilot Ricky's making, is it?

A dollar bill takes a zany trip-with the Ricardos and Mertzes in hot pursuit. It's a winning bill (worth $300) in a newspaper contest. It belongs to Ricky, but he gallantly slips it into Lucy's purse. Gallant isn't necessarily smart: Lucy unthinkingly gives the bill to the grocery delivery boy-who gives it to Ethel in change. The wild ride has only begun!

Lucy writes a novel in which the characters are thinly-veiled caricatures of Ricky, Fred and Ethel. Too thinly veiled, Ricky, Fred and Ethel think. So they burn it. But not before Lucy gets a copy to a publisher.

It's redecorating time at the Mertzes', and Lucy and Ricky volunteer to help. But when Fred turns on a fan as Lucy is unstuffing a chair, the paint and feathers they were using go flying. Lucy feels responsible for the ruined furniture, so she gives Ethel her own living room furniture as a gift.

Lucy finally gets her chance to be in show business, when she tricks Ricky into letting her do the "Jitterbug" in one of his shows. She's terrific during rehearsals, but problems occur when Lucy accompanies Ricky (who's been suffering from headaches) to the eye doctor just before the show. There, the doctor decides to examine Lucy's eyes, as well. He puts some eyedrops in Lucy's eyes which "relaxes" them, but Lucy's vision is blurry for the next twenty four hours. Naturally, this causes problems since Lucy has to perform that night.
