Corrected entry: The location of Evergreen Terrace and the Simpson home changes dramatically. In 'Homer the Great' the power plant car park runs past the Simpson's backyard while in the rest of the series its in the middle of a housing estate. In 'two bad neighbours' and other episodes there is a row of houses opposite the Simpsons, while in some episodes the Simpson's house is visible without opposite houses.
Corrected entry: When Marge is sitting awake in the darkness, Homer says, "Marge could you close your eyes? I'm trying to sleep", because of the brightness of her eyes, gleaming in the dark. There was just darkness where Homer was sleeping, indicating his eyes must have been closed, so how would he have known that Marge's eyes were open?
Corrected entry: Throughout the episode, Chief Wiggum acts rather dilligently in his attempts to track down and capture Mona Simpson. But when Mona first appeared (7-8: Mother Simpson), Chief Wiggum was the one who tipped her off and enabled her to escape. He was grateful to Mona because her break-in at the germ warfare lab inadvertently cured his asthma.DavidK93
