An ancient sitcom plotline is given a new lease on life in this episode. It is the last straw for Debra (Patricia Heaton) when an uninvited Marie (Doris Roberts) crashes and ruins her Tupperware party. Rather than tell off Marie then and there, Debra pours out her anger in a letter. Terrified by the potential fallout of Debra's vitriol, Ray goes to great and near-impossible lengths to prevent the letter from being delivered. Among the guest stars is Nora Dunn, the former Saturday Night Live regular who made headlines when she refused to appear on the same SNL stage with comedian Andrew Dice Clay.
