In having Chachi come to live and work with him, Fonzie grows too, becoming an overall better, more responsible and caring person. These are just a couple examples of Fonzie and Chachi's relationship.Fonzie serves as Chachi's best man when he marries Joanie. The last couple seasons show how close Fonzie and Chachi really grew to be.She was the only person Fonzie allowed to address him by his first name, Arthur, which she always did affectionately.
At the beginning of the series, Fonzie is a high school dropout, prompting establishment characters in the show to see him as a rebel and bad influence.
Fonzie is shown once attempting to go back to school with Richie, but he later decides it just isn't for him and drops out again.
While confident with women, he blushed whenever Marion ("Mrs.
C." to Fonzie), who became like a surrogate mother to him, kissed him on the cheek.
Arthur Fonzarelli was born to an Italian-American family. When the senior Fonzarelli disappeared, he left a locked box for his son, but not a key; the young Arthur did everything to open the box before finally repeatedly running over it with his tricycle, only to reveal that it just contained the key to the box.
The only advice Fonzie remembered his father giving was "Don't go out in the rain in your socks." In the Season 6 episode "Christmas Time", a sailor delivers a Christmas present ostensibly from his father (played by Eddie Fontaine), who wishes to make amends.In a later episode, Fonzie unexpectedly meets a woman he believes is his mother in a diner.She convinces him she is not, but in the end, she looks at a picture of Fonzie as Grandma Nussbaum appears to have been a primary caregiver to Fonzie through the age of six.Fonzie is resentful, but at the end of the episode he opens his father's letter explaining why he left and reads it.He also learns that the sailor was his father, who admits in the letter that he doubted he would have the courage to reveal the truth to his son.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. Fonzie regards Richie's two best friends, Ralph Malph and Potsie Webber, as nerds; largely because of their willingness to do virtually anything to fit in.
