In this final episode of Season Three, Arnold is thrilled and excited that he is about to be married to a lovely Japanese girl named Momo. (Nobu McCarthy). Very happy at his soon-to-be marital status, Arnold asks his good friend Fonzie if he will stand up with him and be best man. Although Fonzie is very fond of Arnold and touched by the offer, he feels that he has to say no due to what he calls 'The Fonzarelli Curse' whereby things always go wrong at weddings in which Fonzarellis play an important part.
It seems that Fonzie is right when Momo suddenly calls off the wedding, leaving poor Arnold very unhappy.
There are quite a few laughs in this one, mostly courtesy of the very funny Pat Morita as Arnold but overall, it's not as good as many others in the season have been.
