Grandma Nussbaum appears to have been a primary caregiver to Fonzie since the age of six. When he (instead of Grandma Nussbaum) moves into the Cunninghams' garage apartment—a plot development that helped precipitate his increased presence in the series—he turns his old apartment over to his grandmother. She is rarely referred to after that but she is featured in at least one later episode. Grandma Nussbaum (and she alone) calls Fonzie "Skippy". She is also the grandmother of Fonzie's cousin Chachi. Fonzie's devotion to her foreshadows his ongoing devotion to mother figures throughout the show, particularly to Marion Cunningham, whom Fonzie affectionately calls "Mrs. C." For example, when Marion feels her family no longer needs her, she learned the ways of the world from Fonzie, and Fonzie learned about the closeness of a tight-knit all-American family from the Cunninghams. Though at first looked down on and mistrusted (a result of his past and being a high school dropout), he eventually became accepted by the Cunninghams (his friend Richie's family), even more so after he rented an attic room over their garage. Even Richie's father, Howard ("Mr. C." to Fonzie and the most resistant to him living with them), a pillar of the community, came to regard Fonzie with affection and said "Ayyyy" when Fonzie moved into the garage. Fonzie shares a very close relationship with his younger cousin Chachi. They often had plots in the episodes together, especially after Richie left the show. Fonzie was able to be the older brother figure that Chachi needed in his life. In having Chachi come to live and work with him, Fonzie grows too, becoming an overall better, more responsible and caring person. Fonzie serves as Chachi's best man when he marries Joanie. In the long shot at the end of Chachi and Joanie's wedding, Fonzie is the first person who comes to congratulate his younger cousin. He and Chachi embrace for several seconds. They share another hug at the end of Mr. C's toast. These are just a couple examples of Fonzie and Chachi's relationship. The last couple of seasons show how close Fonzie and Chachi really grew to be. Fonzie seems to respect people brave enough to stand up to him, as evidenced in the episode where Richie recalls meeting Fonzie for the first time while he was a member of a gang called the Falcons.
