Good ads are rare. Ads that strike a chord based on a grain of truth are like uncut white diamonds. This ad from Mass Mutual is just that. We all come to a point in our lives when we tussle with our parents over picking up the cheque after a meal. This ad shows this little struggle and also goes one step further. It shows what goes in the minds of a father and son as they fight over the bill. It's cuteness personified. And yet, it's solid marketing. Insightful, thought-through and hence, effective.
