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.
