Family Troubles.

Janet feels that her parents don't love her anymore because they made her older sister the definite center of attention during her aunt's visit. The gang volunteers to help Janet become "adapted" by another couple and choose elderly Mr. and Mrs. Jones as potential candidates. The Jones quickly realize that Janet is a runaway and decide to teach her and the gang a lesson. They agree to adopt her but make her life a living hell by forcing her to scrub the kitchen floor (which causes Janet to wail, "Why did I ever leave home?")
