Rusty plans to try out for Little League—Danny decides he wants to coach. Danny gets the job, but later has a tough decision to make.

Danny gets the engagement of a lifetime—the London Palladium—and his agent even got them to include his family’s expenses to come with him. Unfortunately, it’s scheduled just when Rusty is about to get initiated into a club, Terry has a date to go to the junior prom with the most popular guy in school and Margaret has been elected regional president of the PTA, and has an announcement party for it to attend.

Danny gets carried away with Margaret's accounts of sightseeing in London. He begins to dream that he is Robert Browning.

Terry and her friends plan a party, which they wanted to plan and put together all by themselves—without the help of adults, and Danny takes over.

Margaret's mooching cousin, Carl, visits the Williams. He quickly moves in, and makes Danny very upset. Danny finally puts his foot down, and reshapes his character. The once lovable Carl becomes a hard worker, but he is no longer any fun. Danny finally gives in to his children (and Margaret), and Carl becomes as lovable as ever.

Danny’s old Vaudeville pal comes to town and asks him to give his son a leg up in show business—but his son’s heart isn’t really in it.

Controversy brews at the Williams house while Uncle Tonoose visits. When Terry is not tapped to join a soroity she would like to join due to her heritage, her uncle teachs her a big lesson.

Danny asks his friend, Songwriter Harry Ruby, if he can recommend a piano player who can be an accompanist on Danny's USO tour.

Danny showers the children with money to give them a hint about getting a present for his birthday. But the children don't know,and spend it on the custodian of the building, who was once a sailor. They buy him a shirt. In the tag, the children perform a play due to Danny's love of the arts.
