They then decide to rent their sons' old bedroom to a college student and place an ad in the campus news.

The ad is answered by Jennifer McKenzie (Brenda Sykes), a sophisticated, neat and studious college student, who speaks to Harriet over the phone.

After Harriet tells Jennifer (who was renamed “Brenda” after the pilot episode) that the room is available, she sets up a time to come to the Nelsons house.

Despite their differences, the girls become fast friends and are soon considered to be part of the Nelson family by Ozzie and Harriet.

The series ended after a single season, as Ozzie Nelson began experiencing health issues.
