On Grandpa's birthday, Phyllis and George give him and Grandma a gift, a romantic weekend at the Plaza Hotel--an excursion the Bergers consider until Nathaniel contracts chicken pox. Sophie takes over his care with such vigor, overruling all of Phyllis' instructions, that Phyllis feels thrust in the background of her own child's care and her anger precipitates a quarrel between her and her mother. Meanwhile, Benny stakes out an apartment building in hopes of seeing his favorite baseball player, Duke Snider.
