Robbie enrols in the University and is totally captivated by a blonde girl, and Uncle Charley is initiated into the rapid-fire procedure of shopping in supermarkets. The family...

Robbie Loves Katie

After advice from his father who tells him it isn't right to tie himself down to one girl, Robbie Douglas, intending to break off his romance with Katie Miller, ends up proposing to her. Soon his heart over rules his head and he buys an engagement ring and sets a wedding date.

Inspection of the Groom

Robbie and Katie pick a wedding date two weeks off. Katie's sorority sisters decide to do some private investigating on their own. Prospective groom Robbie then undergoes the complete once-over by his fiancee's family and runs the gamut of numerous cousins, aunts and a crotchety grandmother.

Countdown to Marriage

The day before her wedding Katie Miller feels she faces complete disaster. When Robbie tries to console her, she flares up at him and after a short argument, the pair declare the wedding is off. Of course, Grandma Collins thinks otherwise.

Early on his wedding day, Robbie Douglas and his family are peacefully oversleeping. They awaken just in time and scramble madly to get ready as Robbie and Katie are soon married amid traditional confusion and tears. The lost family dog, Tramp, returns in time to join the family in the front pew.

Robbie and Katie come home from their honeymoon to face the problems of newlyweds in a previously all-male household. Katie finds her role difficult, for Charley insists on continuing as the family cook and attending to all the laundry. Robbie becomes worried about her frequent weeping spells.

My Wife, the Waitress

For their fourth week wedding anniversary, Katie decides to earn some money for an expensive gift for Robbie by taking a one week job as a tea-room waitress. Robbie lunches at the tea-room and finds Katie, who has taken over as a last-minute replacement for the cigarette girl, in an abbreviated cos...

At school, Ernie meets Mike, who offers to play with him, but the family is exasperated to know Mike likes tomboyish pranks. Then there's a problem persuading Ernie to accept his new friend when he learns that she's really a girl.

Designing Woman

Attractive lady engineer Eileen Talbot is assigned to help Steve Douglas on a rush project in his office, and she applies her many talents to assure romantic, as well as technical success. Only level headed Katie recognizes her as a manipulating female long before the gullible male Douglases do.

Ernie, the Bluebeard

Chip learns the meaning of empathy when he helps Ernie out of a predicament when he somehow winds up with two dates with two different girls for the same dance, when he doesn't even like girls to start with.

One stormy night while Steve is in San Francisco, Katie is alone in the Douglas house while the rest of the family is attending a ballgame. Her tenseness builds as late in the night she hears a scary rythmic noise, and hysterically calls Steve to report that the family has not yet returned and that...

The Computer Picnic

Chip manages to outwit the machine age when a computer is used to select partners for picnic dates for the boys in his class and girls from another school. He is soon startled to find that his date, although sweet and likeable, is six feet tall.

The Aunt Who Came to Dinner

Katie is worried when Steve invites her visiting Aunt to spend a week at the house while he is out of town. Before long, she is molding the entire household into her image of a cultured family. When she slips some money under Katie's pillow, the girl angrily announces that this behaviour cannot cont...

Leaving the Nest

When minor irritations arise in the Douglas household, Robbie and Katie move temporarily into a borrowed apartment while their friends are away. Their life is complicated by the absence of a coffee pot, a pull-down bed that won't go up and the lack of a television set.

You're Driving Me Crazy

Chip Douglas is so nervous about taking his driving test that his new sister in law Katie decides to help by taking the test with him. Soon after they both get their driving licenses the family car collects a big scratch, but neither will plead guilty.

Chip invites his neighbour's long-haired, guitar playing boy from Liverpool as a key addition to his off-key rock and roll band. The English lad's soft, folksong guitar is a disappointment and obviously won't work with the raucous amplified trio, but he helps them to win a trophy in an amateur talen...

With his father Steve busy over the weekend, Chip suggests that newlyweds Robbie and Katie act as chaperones to him and his friends at a mountain cabin. At Katie's insistence, Robbie keeps strict checks on the three teenage couples.

Green-Eyed Robbie

Robbie Douglas displays a bit of jealousy when his bride innocently agrees to tutor a handsome student. Later, Katie confides to Uncle Charley that he was once her steady boyfriend, and Charley off-handedly warns Katie to be careful because Robbie has a jealous nature.

Katie tearfully complains when Uncle Charley makes her feel unnecessary in the Douglas household. Steve speaks to Charley who is flabbergasted at the accusation, but immediately makes amends. Meanwhile, Chip is on a five-man school committee; four of the 'men' are girls and they won't let him open ...

Ernie, the Jinx

A series of strange coincidences make young Ernie feel he's a jinx to anyone he contacts, but his father assures him that he has a loyal family who loves him in spite all of his trouble, and that they will stick by him no matter what.
