Homer surprises the family with a newly decorated basement, now a recreation room, prompting
Marge to ask how he could afford all this. He tells Marge he has a plan, and he files for bankruptcy because he believes that this will save him from paying his debts. Unfortunately,
Judge Constance Harm tells him that the bankruptcy laws have changed, and, under the new laws, he must pay everything back. Looking through the family's expenses, Homer decides to save money by moving
Grampa out of the retirement home and having him live with the family. Grampa turns the recreation room into his bedroom. Without the recreation room,
Bart and
Lisa decide to order complimentary cardboard delivery boxes to build a fort after seeing
Ned order some boxes. When the box deliveryman sees what Bart and Lisa did with the boxes, he demands they return them, and he threatens them when they refuse. An army of deliverymen arrive to battle Bart and Lisa at their fort. As they scale the fort,
Nelson comes to the rescue of Bart and Lisa. They fend off the army but decide to melt the fort with water from a hose when they get bored with it. One night, Homer and Marge go out and ask Grampa to babysit Bart and Lisa. Not trusting Grampa's competence, Marge also asks her sister
Selma to watch Grampa and the kids. During the evening, Grampa and Selma bond and end up kissing as Homer and Marge arrive home. Marge is happy with Grampa and Selma's decision to date, but a disgusted Homer and
Patty team up to break them up. At the mall, Patty, disguised as Selma, kisses a disguised Homer as Grampa passes them. Grampa is saddened until the real Selma appears and exposes them. Angry at being manipulated, Grampa proposes to Selma and she accepts. They get married and move in together. With Grampa unable to work, Selma works as a manager at the DMV while he stays home and takes care of her daughter
Ling. One day, Grampa gets confused while using the kitchen appliances and causes a fire. This makes Selma realize their relationship cannot last just with love, but as she laments that she will be alone forever, Grampa assures her she will find someone she can depend on, and they dance together one last time. ==Production==
