Our reading
An editorial interpretation.
The speaker dismisses another woman's intelligence and predicts that gravity will eventually get her. One reading hears a spiteful reference to ageing and appearance. The joke uses the impersonal language of a physical force to express personal resentment, making the promised comeuppance sound inevitable.
