S6 E17: Mary Loves Scoochie (1)

Dick discovers that Mary has been receiving elaborate love letters from a mystery man named 'Scoochie' and confronts her about it. She reveals that she has been receiving them for years but has no idea who Scoochie actually is, so Dick pretends that it has been him all along. This goes wrong, however, when the real Scoochie arranges to meet Mary at the Medieval Festival. Meanwhile, after another alien unit operating in Ohio wins an award over the Solomons at the Alien Award Show, Sally and Harry make it their mission to track them down, and eventually move in with an Amish family, who they believe to be the other unit, since they are so different.
