Carmine (Eddie Mekka) knows where Laverne (Penny Marshall) and Shirley (Cindy Williams) can pick up a used couch for next to nothing. Unfortunately, the couch is somewhere within an allegedly "haunted" house--and when the girls show up to claim the couch, they are locked into the spooky old mansion, as their friends and loved ones disappear all around them! Of courses, there's a logical--and rather touching--explanation for the mysterious goings-on, and all ends happily thanks to the unexpected intervention of Abraham Lincoln. ~ Hal Erickson, Rovi
