In Nike's latest promotional ad, titled, "Fly Swatter", tennis legend Roger Federer is put to the test against a familiar foe. No it's not Rafa, or Djokovic, but the common housefly. Like Federer, we've all used whatever's at arm's reach or at our disposable to get rid of the annoying insect. Unlike Federer, many of us haven't been in this situation with the extremely flexible Nike Free Trainer 5.0 as a weapon of choice. Check out the video as Federer puts his familiar tennis moves on display in his bid to rid his domicile of this nuisance. Bzzzzz! Bzzzzzz!
