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.
