Factual error: In the scene Laura and Sally are about to go to the bedroom, Buddy and Rob are going to sleep in the living room of the haunted cabin. Rob and Laura tell Buddy and Sally things like how he steals the pillow and he takes all the covers at home. However at home, they sleep in twin beds so they shouldn't know such things. This is true. However, they do have a son. They had to share a bed at least once in their marriage.

Plot hole: In the episode "That's my Boy" when they bring Richie home from the hospital, Rob and Laura are living in the house they have for every show.
