My Three Sons - Season 8 (1967)

It's the night before Robbie (Don Grady) and Katie's (Tina Cole) wedding and, everything that can go wrong, does. First, Tramp runs away and can't be found. Next, the dressmaker sends the wrong gown and bridesmaids dresses to the Douglass house. Topping things off, Robbie and Katie have an argument and decide to call the wedding off. Will Robbie and Katie get over their jitters and make it to the altar? Also, will anything else go wrong before the wedding?

The Douglas clan oversleeps on Robbie (Don Grady) and Katie (Tina Cole)'s wedding day and chaos reigns as they get ready. Meanwhile, Robbie's best man falls ill and Chip (Stanley Livingston) is recruited to take his place. Tramp is missing and arrives at the church just in time for the ceremony.

Robbie and Katie return from their honeymoon and everything seems to go wrong for Katie as the Douglas clan adjusts to the fact that their all-male household is no longer all-male.

Katie learns that Robbie is buying her a gift for their four-week "anniversary" so she gets a waitress job to earn money to buy a gift for Robbie. As luck would have it, Katie has to fill in for the cigarette girl - skimpy outfit and all - the same day that Robbie's friend wins a free lunch at the restaurant. Naturally, Robbie blows his top when he sees how Katie is dressed, but Steve intervenes to patch things up between the newlyweds.

Ernie's new playmate, Mike, likes to pull childish pranks that upset the Douglas family. Robbie goes to talk to Mike's parents only to learn that Mike doesn't have a mother, and that Mike is actually a girl named Michelle! Unfortunately, Michelle's father treats her like his son rather than his daughter, only talking about sports and other "boy" things, so the Douglases try to bring out her feminine side.

Attractive lady engineer Eileen Talbot (Anne Baxter) is assigned to help Steve Douglas (Fred MacMurray) 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 (Tina Cole) recognizes her as a manipulating female, long before the gullible male Douglases do.

Ernie (Barry Livingston) has innocently traded trinkets with two girls, and now they both assume that he is her boyfriend and will be taking her to the upcoming "Gym Dandy" school dance. Ernie doesn't want to go to the dance at all, and tries to get out of his dates, but each of the girl's parents insist that Ernie take their daughter to the dance. When both girls show up at the Douglas home the night of the dance, Chip (Stanley Livingston) steps in to escort one girl (Claire Wilcox) (who is thrilled to be with an "older man"), while Ernie escorts the other (Maureen McCormick).

While Steve is away on a business trip and the guys are out at a sporting event, Katie is awoken by a storm and hears an eerie, heart-beat sound. She phones Steve in a panic. The gang returns and are also spooked but can't figure it out.

Chip's (Stanley Livingston) class uses a computer to match kids for dates, with kids from another school, for the upcoming "computer picnic". Chip is excited about his date (Eva Ein) - until he meets her and discovers that she's about a foot taller than he is. Chip is willing to go through with the date, but the girl realizes that Chip is very uncomfortable with the situation, and suggests that they call it off. So Chip and his buddies get together and swap their dates, based on more personal preferences, - pleasing Uncle Charley, who dislikes the newfangled computer dating. Chip ends up ...

Katie's (Tina Cole) snooty Aunt Cecile (Marsha Hunt) visits the Douglas home and clearly doesn't fit in - trying to make everyone act more refined and calling them by their given names. Luckily for Steve (Fred MacMurray), he's (surprise) headed out of town on a business trip. The rest of the family isn't so lucky, as now Cecile can stay over in Steve's room for an entire week.

With Katie now living with the Douglases, everyone finds that they are getting in each other's way a lot more often. Newlyweds Rob and Katie take the opportunity to move into a friend's apartment while they are away, but soon find that they miss what they had at home.

Chip is nervous about his upcoming driving test, so Katie asks Rob to teach her to drive so that she and Chip will be learning together. Katie has difficulties learning from Rob, and Chip wants to drive like a maniac while Steve is teaching him to drive like an old lady. Both eventually pass their driving tests and Steve lets each of them borrow his car - which returns with a mysterious huge scratch for which nether driver is willing to take the blame. Luckily, an honest kid comes along with his father to admit that he was responsible for the scratch, but the ...

After discovering that a neighbor (Dianne Ramey) has a cousin, visiting from Liverpool, who plays guitar, Chip (Stanley Livingston) invites the cousin to join his band, only to discover that he has a much more laid back, folk style than Chip assumed. But the new member (Jeremy Clyde of Chad and Jeremy fame) is just what the band needs, in order to win the top award at the local teen club.

Robbie and Katie serve as chaperones for a group of high school students, including Chip, on a trip. Much to Chip's consternation, Robbie manages to foil every plan they come up with to sneak away, including removing the car's rotor from inside the distributor so it won't start.

Katie (Tina Cole) becomes a tutor to earn some extra money and is surprised to learn that her first student, Craig Benson (Charles Robinson), is not only a male, but a handsome ex-boyfriend of hers. Robbie (Don Grady) doesn't mind at first, until he learns that the pair took a break from studying without his knowledge. A spat breaks out, and Robbie ends up sleeping on the couch, until both of the newlyweds realize they were partly to blame.

Katie (Tina Cole) complains that Uncle Charley (William Demarest) is making her feel unnecessary in the Douglas home. Steve (Fred MacMurray) speaks to Charley, who tries to makes amends by planning a rather bizarre "tea party" on Katie's behalf. Meanwhile, Chip (Stanley Livingston) volunteers for the school dance committee, but the otherwise all-female committee frustrate Chip by ignoring his ideas. However, the girls want to help out after Chip tells them what Uncle Charley is planning for the tea party - party balloons and donuts for dunking are out, scones, silverware and napkins are in. Much to Katie's surprise, the tea...

Ernie becomes convinced he's a jinx when things inexplicably start to go wrong whenever he's around, but Steve reassures him that his family loves him anyhow.

Ernie meets Zsa Zsa Gabor after accidentally falling into her swimming pool. She befriends Ernie, who introduces her to the rest of the Douglas clan.

Uncle Charley buys an 11-year-old trotting horse, thinking of the potential purses that the horse could win. With Charley himself driving the sulky, the horse wins his qualifying race, but he discovers his horse's opponents were run-down nags more qualified for the glue factory than competitive racing. So Charley retires the horse at a friend's stable, where Ernie can ride him whenever he wants.

Robbie reports to camp for two weeks of military reserve maneuvers, and Katie decides to go along and stay at a nearby motel so that the newlyweds can be near each other. Meanwhile, Uncle Charley and the boys are camping at Yosemite, which also happens to be close to Robbie's camp. During a stroll, Katie wanders into the mock battlefield and gets arrested by Robbie's unit. Later, each of the other family members try to locate Robbie and similarly get detained. Steve heads toward camp to prevent the family from interfering with Rob's duties, but he manages to get ...

Uncle Charley is in charge of Frolics Night at his lodge, but has trouble lining up the entertainment, so Charley joins in with his lodge brothers, dressing in drag for a chorus line number.

The Wong family from Bryant Park drops in on the Douglases unexpectedly while on their way to Hong Kong. Since the hour is late, Steve invites the Wongs to stay overnight, forcing him to cancel the family camping trip planned for early the next morning.
