“Mean” Joe Greene, a four-time Super Bowl champion with the Pittsburgh Steelers, stars for Procter & Gamble in a Super Bowl redux of his classic Coca-Cola commercial, which is regarded as one of the best Big Game spots of all time. Instead of Coke, however, the product here is Downy’s Unstopables, which is used in washing to provide long-lasting freshness. The commercial also stars comedian Amy Sedaris.
