With only a week left in Hollywood, Lucy weeps about her lack of souvenirs. Her collection already includes a tin can run over by Cary Grant's rear tire, a napkin boasting Lana Turner's lip-prints, and a few other goodies. But when Lucy discovers that John Wayne's concrete block at Grauman's Chinese Theatre is loose, she decides to take home a souvenir to end all souvenirs.

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. Boyer is at a nearby table, and when Lucy and Ethel spot him they immediately repair to the ladies room to plot their approach. 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.

Ricky is opening a new club, and he wants Bob Hope to appear at the grand opening. Lucy fears Hope won't appear because of her widespread reputation for monkey-wrench throwing, and wants to reassure him that this time she's butting out.

Little Ricky gets drums and the Mertzes get headaches. So do Lucy and Ricky, but they're not about to evict themselves.

Lucy tries to get in a skit with Orson Welles at Ricky's club, thinking it is a Shakespearean play that he will be doing. When Orson Welles tells Lucy she can be in the show, she calls her old high school drama teacher to tell her the news. Lucy's old teacher sends her whole drama class to Club Babalu to see Lucy perform. But poor Lucy! It turns out Welles only wanted her to be his assistant for a magic trick.

Little Ricky is scheduled to play the drums in a children's orchestra. Although his parents and their friends the Mertzes are overcome with nervousness, Little Ricky seems calm until his big moment arrives; then he goes to pieces. His next performance is six months away, but Lucy feels she must do something about his stage fright now.

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

Colorized version of the Christmas show

The Ricardos and Mertzes spend Christmas Eve decorating a tree - and remembering moments that led up to the birth of Little Ricky five years earlier.

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.

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.
