In the first episode of a two-part story, a nervous Archie steels himself for a gall-bladder operation. His fears are not allayed by the fact that the hospital is festooned with ethnic minorities: His nurse is Puerto Rican, his doctor is Jewish, and he is compelled to accept a blood transfusion from a black Caribbean woman. Liz Torres makes her first series appearance as Teresa Betancourt. Others in the cast include Milton Selzer as Dr. Shapiro and Vinnette Carrol as Dr. Wynell Thatcher. Written by Milt Josefsberg and Mort Lachman, part one of "Archie's Operation" first aired on October 20, 1976. ~ Hal Erickson, Rovi
