Corrected entry: At the very end when Homer runs out of Moes there is no street and only a grey wall. (00:21:20)
Corrected entry: While Lisa gives her speech at school, Miss Hoover seems to have only one leg. (00:13:20)
Correction: Her other leg is obviously raised and the flat of her foot is leaning against the desk. We can't see it because of her long skirt.
Correction: We can't see any detail to know what's outside. It simply looks as if it's dark so we can't see anything.
