Fonzie reads Hot Rod magazine at a booth at Arnold's while Ralph and Potsie argue over football. Arnold announces that the drive-in will be closed next weekend because he is getting married to a Japanese girl named Momo Okamoto. It is an arranged marriage, and they had been exchanging letters and pictures. Arnold asks Fonzie to be his best man, but Fonzie doesn't appear excited about it. He tells Richie about the Fonzarelli Curse (he had been best man twice, and both weddings were disasters). Momo and her chaperone, Terukazu, come to the Cunningham house to stay. Joanie shows Momo where she will be staying. Arnold comes in and says he thinks Momo hates him because he is not a successful American businessman. Howard suggests that Arnold bring her to the restaurant to show her what a success he has become with Arnold's. At Arnold's, Momo runs off crying and, later, calls the wedding off. Marion explains that Momo thinks she is still very Japanese and would hold Arnold's career back. Marion orders Fonzie, in no uncertain terms, to talk to Arnold. Fonzie gets Arnold together with Momo at the Cunningham house to talk. Arnold says he was raised in the oriental culture and wants to have an oriental wife. Richie gives Fonzie the address to get his kimono for the ceremony. The wedding is the next night at Arnold's. The Cunninghams meet Aunt Sumi, the family's matriarch in America. Potsie sings a song that he wrote, and Aunt Sumi tears it up. Fonzie finally arrives. The wedding commences, and Arnold has Fonzie read a welcome message in English and Japanese.
