When Lauren is required to write a paper on the typical American family, she chooses the Keatons. Focusing first on Steven and Elyse, she asks about their history together and the growth of the family, prompting Elyse to reminisce about her pregnancy... (more) with Andy. Steven recalls what a thrill Andy's arrival was to everyone, especially Alex, who was delighted to finally have a brother. As the family discusses the ways in which little Andy changed their lives, they recall just how protective and involved Alex became in the upbringing of the baby. While on the subject, Jennifer remembers the time that Steven decided he wasn't spending enough time with her and tried to become her "pal".
