After department store Santa Gil is fired for giving a tearful Lisa the last Malibu Stacy Pony Barbecue set - which the store owner had ear-marked for his daughter - Marge feels sorry for him and asks him to stay for Christmas. Due to the Simpsons' inability to say No he ends up staying for eleven months before moving to a top job in realty in Scottsdale. Seeking closure, Marge follows him and gives him the telling-off she has been suppressing for months but in front of his staff,and it costs him his job. so the Simpsons buy him a house in Scottsdale and spend Christmas with him.
