Synopsis
Christmas is approaching. While out shopping with Roz and looking for a menorah for his son Frederick, Frasier attempts to covertly purchase a sweater for her. Just before Roz realizes, another woman, Helen Moskowitz, rescues Frasier by pretending that she is buying it. Helen recognizes him from the radio, and suggests a date with her daughter, Fay. The reluctant Frasier is pleasantly surprised when he meets her, although she is embarrassed at being fixed up by her mother.

Things go well between them, and Fay visits Frasier's apartment with Helen on the way to the airport. Frasier learns that Fay believed he was Jewish, and although this is not a problem for her, she fears her mother will disapprove. He agrees to hide the Christmas decorations and pretend to be Jewish, with Niles and Martin also doing so. The deception proves tricky to sustain, as Eddie appears dressed in a Santa Claus costume, a deliveryman brings a Christmas tree, and Daphne is busy organizing a holiday revue downstairs starring Niles dressed as Jesus.
