I made a supreme effort not to do that thing that parents do, which is to bore people without children to death by going on and on about how funny their children are, so there’s none of that hopefully.

Jo Brand’s line is a self-deprecating, audience-aware joke about a familiar social dynamic: parents’ tendency to monopolize conversation with anecdotes about their children, assuming universal interest. By calling it a “supreme effort,” she frames restraint as both difficult and virtuous, acknowledging how powerful parental pride can be while also validating the impatience of non-parents. The humor comes from the exaggerated fear of “boring…to death” and the hedging “hopefully,” which undercuts her own promise and keeps the tone conversational. The quote also reflects Brand’s comedic persona—wry, candid, and attentive to everyday irritations and social etiquette.
