Fellow Spaniards Pau Gasol and Rafael Nadal star in this watch ad where they fling balls at each other's faces, presumably to win the affections of a hot lady with a cool box. Interesting stratagem. This commercial is apparently from a while ago, but it's new to the English-speaking world and, hey, Nadal just won the French Open and Gasol is playing shitty in the NBA Finals, so it's just relevant enough to work. And their last names rhyme. People love things that rhyme, like cock and Alfred Prufrock.
Since I don't speak Spanish, I'm assuming the hot chick says "Guys getting balls to the face makes me hot. If you do that, you can touch my box. It has expensive watches in it." They do so, whereupon they retire to the sexing boat, where the woman beds Gasol, but rejects Nadal for wearing that fruity sleeveless shirt.
