Bub and Mike are excited for their lodge and fraternity initiations.

Mike tries to learn Spanish by sleeping with a Spanish tape playing under his pillow. When he goes on a trip, Steve sleeps in Mike's bed since his own room is being painted. The auto timed recorder plays; Steve talks Spanish in the morning.

Robbie (Don Grady) is assigned the new glamour girl (Judi Sherven) as his study partner. He finds there's more to a study partner than good looks.

When the boys continue to ask Bub for help with their homework, he realizes he does not have all the answers. He decides to go to night school for further education. He meets another student, and they both make up stories about their lives.

Robbie starts a musical band, with practice at his house. The other Douglases cover their ears to drown out the noise. Steve helps them get in tune and even plays saxophone. When Mike's class needs a band for a dance, Robbie wants the job.

Robbie feels like he is always following his brother's footsteps at school, so when it is time to join a club, he picks one that Mike never joined.

Chip runs away from home after feeling neglected, but when he gets downtown, he realizes home is safer.

While on a camping trip vacation without the other family members, Steve is matched to another camper by an older couple who loves to play matchmakers. Both Steve and Fran are initially reluctant.

Mike and Robbie each have dates the same night. Due to a mix up in names, Mike picks up Robbie's young date (Trudi Ames), and Robbie picks up an older woman (Carole Costello), meant for Mike.

Chip needs a drawing for open house at school and finds the family circle a pretty rough bunch of critics. He decides a sailboat picture of Bub's beats his own efforts, and he borrows it.
