Edith prepares a special farewell dinner for Mike and Gloria, in preparation of their move to California. While Gloria eagerly looks forward to this final family get-together, Mike has a problem: He has already made a commitment that evening to meet his new supervisor from Santa Barbara. The first episode of a two-part story, "The Dinner Guest" was written by Mel Tolkin and Larry Rhine, and first aired on March 12, 1978. ~ Hal Erickson, Rovi
