Riley's mother Donna called five times before his naive kid sister Jenny arrives, and she sure is a pot-plant, still engaged to Jeremy, her first boy-friend ever since Kindergarten. Josh and Allison make fun of Jenny, Fran takes her shopping as the girlish daughter she never had, to be told her taste is too slutty. Fran sends Josh to show Jenny New York, but they only return after a night when they 'accidentally' got married as drunk wedding witnesses for a couple they just met in a bar. Riley and Fran blame each-other as bad examples. Choosing a legal reason for annulment is painful for poor 'crazy' Josh.

When a waitress flirts with Riley at Fran's birthday dinner, adding she can see where Josh got his good looks, Fran is down and gets nightmares about all the Reeves family being ancient, fat and ugly, only Ryan still seems a young god at 70. When Riley gets her to see a gynecologist, the verdict is a hysterectomy, which stops her PMS, even if it starts menopause. Ted does the operation which goes well, everyone is at her bedside, but after a nightmare about Riley wasting his young life to take care of her, she breaks up unilaterally, pretending he now makes her feel old.
