Charles Boyer deals with a star-crazed Lucy in this guest appearance. The setting: Paris, where the Ricardos and Mertzes are lunching at a sidewalk cafe.

Ricky tries to stop the assault but nobody can defend against the star-struck Lucy.

In Switzerland, the Ricardos and Mertzes are caught in an abandoned cabin during an avalanche. It’s one of Lucy’s own making (of course), and it leads to some soul-searching and confessions. But not by Ricky: “We might be saved!” They are — by an oompah band playing “La Cucaracha.”

The Ricardos and Mertzes pedal their way from Italy to the French Riviera. It's a bumpy ride, thanks (of course) to Lucy, who left her passport in her purse, which she locked in a suitcase, which she sent ahead to their hotel in Nice. That presents problems when they get to the Italian-French border.

Still on their vacation, the Ricardos go to Cuba, where Ricky wants to introduce his relatives to Lucy and Little Ricky.

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.

The Ricardos' apartment begins to resemble a pet shop when Little Ricky gets a puppy. Lucy and Ricky are both determined to get rid of the puppy after their son brings it home -- as are their landlords, Fred and Ethel. They have a hard time overcoming Little Ricky's arguments that a puppy would be a welcome addition to a home that already boasts a canary, a frog, a lizard, a turtle, and some goldfish.

The Ricardos find themselves, and all their belongings, boarding with the Mertzes while they wait to move into their new Westport, Connecticut home.

The Mertzes find a way to stay with the Ricardos: chicken farming. But the scheme puts Lucy over her head in chickens when she and Ethel bring home 500 baby chicks before the hen house is ready.

Chicken-raising and practicing a tango for Little Ricky's school PTA meeting combine to get the Ricardos and the Mertzes in a verbal battle. It's up to Ricky, Jr. and his neighborhood pal Bruce Ramsey to straighten things out.

When Ricky refuses to bring his rumba band out to Westport to play for a Historical Society benefit, Lucy and the Mertzes put together a combo of their own, with Little Ricky on drums.

Ethel is jealous of Lucy's friendship with Betty Ramsey. But when Betty reveals that she's from Ethel's home town of Albuquerque, the two become fast friends, and now it's Lucy who feels left out.

Lucy has a problem deciding what to do to get her vacationing husband, Ricky, out of her hair so she can do her housework. She and Ethel solve the problem by putting their husbands to work building a barbecue.

Lucy, Ethel, and Betty want their husbands to dance with their friends' visiting houseguest - until they see that she's a sultry, young blonde. Now the boys are only too happy to oblige - and the miffed wives decide to fight glamour with glamour.
