With so much political crossfire lately over the role of mothers, it's great to see the return of Wieden + Kennedy's universally heartwarming "Thank you, Mom" campaign for Procter & Gamble. Originally launched for the 2010 Winter Olympics, the messaging has been dramatically reborn for the 2012 Summer Olympics in London with "Best Job," a cinematic and emotional anthem from Babel director (and sometime anti-meth PSA creator) Alejandro González Iñárritu. The new spot is a beautiful testament to parents around the world who have helped their children through the grueling daily grind toward becoming an Olympic athlete. While the online-only ad and its tagline, "The hardest job in the world is the best job in the world," are likely to get dragged into the political theater of Ann Romney and full-time motherhood, there's also a chance that the spot could finally help settle this pointless debate by reminding us all that any mom who makes the time to support her kids is a great mom.
