Sadie Shapiro, in her third jog-around in the Cute Old Jewish Lady stakes, is here a matchmaker, having inherited a trio of impossible clients from a recently deceased friend who practiced that dying art. (In case you haven't met Sadie and her genial husband Sam--you should only continue to live and be happy--Sadie is a famous knitter, jogger, and supreme fixit.) Back to the three impossibles: wealthy cultured widow Doris, for whom no man could take the place of the late beloved Jacob; seedy widower Harry, who won't wed anyone but Doris (who can't stand him); and young sculptor Brenda Fogelman, who looks a sight and doesn't bathe. Then there's TV producer Maxine, who needs a push toward nice Dr. Michael. And there's also a problem with a girl whose grandmother won't unleash her fruitcake recipe. So nu? Sam cleans up Harry (who's really wealthy and reads books); Sadie sends Brenda to a salon for the works (she snags a TV bigwig); Maxine and Michael get a lecture; Sadie hears grandmother's secret and releases the historic recipe. So listen--it couldn't hurt.
