If aliens watch North American commercials to learn more about earth dwellers, they may make these assumptions:
That mothers excitedly lurk in doorways with Bounty paper towels and bottles of Mr. Clean to clean up their husbands' and children's inevitable and completely preventable accidents involving spaghetti sauce and toy cars,
That women are obsessed with eating yogourt and "treat" themselves to slivers of chocolate cake and low-fat miniature cookies,
That men value beer and football over relationships,
That animals can speak like humans, but without opening their mouths, and they only talk about how much they love food, cell phone plans and insurance,
That most of us are ill,
That we are idiots,
That there are too many commercials.
Unless these are sociologist aliens who know that commercials don't reflect reality and that corporations think (or know) that women may be more likely to buy yogourt if they are made to feel that they need to lose weight and that yogourt will help them do that.
