Sarah tells her boyfriend about Harry and jeopardizes the Hendersons' secret, and her love life, when she invites him to dinner.

Hoping to join the "cool" contingent at school, Ernie arranges for Harry to be school mascot for Madison Junior High.

When Sara's stage production of "Beauty and the Beast" lacks an actor to play the Beast, George gets an idea and Harry becomes Sara's co-star.

Ernie explains his moussed hair and missed classes as follows: "I'm a man now. I've got my own trail to blaze." However, in the path of every pubescent pioneer is a protective mother.
