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's husband runs.

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.

Lucy is delighted to learn she is pregnant—but how to tell Ricky? At lunch, he's too preoccupied with work to listen to her, then it's off to the club, where Lucy finds the right moment and just the right way to tell him.

When Stevie Appleby, Caroline's son, has a birthday party the same day as Little Ricky's, Lucy looks for unusual entertainment to lure the children. Ricky remembers that Superman is in town, and he invites him. But when Ricky is unable to corral Superman, Lucy is left with no choice but to dress as the Man of Steel herself. George Reeves makes a special guest-star appearance in this episode.

Where's the beef? It's in Lucy and Ethel's new walk-in freezer. 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!

Lucy decides to impersonate some Hollywood notables to impress nearsighted Caroline Appleby, who is visiting from New York. A mixup occurs when Lucy, having introduced her friend to "Gary Cooper," "Clark Gable," "Marlon Brando" and "Jimmy Durante," decides to introduce Appleby to Harpo Marx.

Ricky wants Lucy to try working for a week, so she and Ethel get jobs at a candy factory, where they are totally inept, especially at wrapping chocolates, due to a speeding conveyor belt that has them stuffing chocolates into their mouths, blouses and hats.

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 23% alcohol.
