Uncle Joe has been receiving and sending what appears to be love letters. Kate eventually learns that Joe is writing to Mary Alice Perkins. Kate is upset because Mary Alice stood Joe up at the altar several years ago and ran off with his best man, George Perkins. Joe tells Kate that George has passed away. He also admits he never loved anyone but her, and that he has now forgiven her. It seems she is coming to the Shady Rest to marry Joe. When Mary Alice arrives, Kate is put off by her snobbish ways and meddling. Boo Boo Webster, Mary Alice's lawyer, shows up to give the bride away. As the wedding starts, Dog brings Joe a letter that says Mary Alice has run off with Boo Boo. Everyone is kind of relieved, including Joe.
