Upon finding evidence of the loving 40-year relationship between the elderly couple (Billie Bird, Douglas Seale) who formerly owned the house that she and Sam (Ted Danson) have purchased, Diane (Shelley Long) feels miserable about taking the couple's place. To assuage her conscience, Diane talks Sam into throwing a farewell party for the former owners, complete with "surprise" guests. There are surprises, all right, but not the kind that Diane was hoping for. ~ Hal Erickson, Rovi
