15. The Tree House

Complete story — includes the ending

After seeing a shocked look on his friend Doug Porter's face after he receives " the talk " from his father, Kevin wonders when his time will come. Meanwhile, Jack has a week off from work, and he has nothing to do around the house but repairs, which upsets the balance of Norma's household. So Norma suggests that he and Kevin build a tree house together. Jack lets Kevin help by allowing him to use his power tools and things run smoothly until they go up on the platform to look at the view of the neighborhood. The elevated platform also allows them to catch a glimpse of their voluptuous neighbor Donna (Janet Wood) singing while working her tomato garden. This causes Jack and Kevin to share an awkward moment, especially when Norma invites Donna over for a visit. Norma eventually decides to check on their progress and sees the same view of her neighbor, which makes Norma a little uncomfortable. Channeling Norma's response, Jack then has a different talk with Kevin and admits that he's too old for a tree house after all, which stops the construction altogether. In the final scene of the episode, the platform of the incomplete tree house starts to collapse. Guest-starring: Janet Wood as the Arnolds' neighbor Donna. Recurring guest: Brandon Crane as Doug Porter.'Sean Baca as Craig Hobson. Absent: Olivia d'Abo as Karen Arnold; Danica McKellar as Winnie Cooper.
