The Simpsons - Rome-old and Juli-eh is the 15th episode from the Simpsons season 18 and number 393 overall in the series.

The title of this episode is a pun on Shakespeare's Romeo and Juliet.

When Grampa gets kicked out of the retirement castle thanks to Homer declaring bankruptcy (and discovering that bankruptcy laws have changed), Grampa falls in love with Marge's sister Selma, prompting sworn enemies, Homer and Patty, to team up to break them up. Meanwhile, Bart and Lisa con a delivery man into giving them cardboard boxes for a fort, but the delivery men fight back.
