@Weavillain, you sound like you need to see a character to say that certain thing bothers him to believe this certain thing bothers him. Show producers believe we're intelligent people and detect obvious things.

Actions and expressions say more than words. Lisa calls her siblings stupid and she outrightly called Lincoln dumb in "It's a 4xLoud House" and a dunce in "Room with a Feud". She sounded like she forgot Lincoln gets good school grades without her tutorings. This is clear she looks down on her siblings because they aren't prodigies.
