Synopsis by Hal Erickson
Mary (Mary Tyler Moore) feels sorry for Lou Grant (Ed Asner), who, recently separated from his wife, is about to have a birthday all by himself. In her usual fix-it fashion, Mary arranges a surprise birthday party for her boss. But she hasn't counted upon two things: Lou hates birthdays and he despises surprises. Betty White makes her second series appearance as the sickeningly sweet "Happy Homemaker" Sue Ann Nivens. "Happy Birthday, Lou" originally aired on December 22, 1973.
