The gift of a laugh (or several), presented to you by HEAD Tennis and Novak Djokovic, with a little help from poodles, boy bands, seals, Navy SEALs, air bourne water tanks and two commentators.
This viral is popularly known as the 'HEAD commercial' or the 'HEAD Speed Viral'. Note the difference between how he first celebrates the shot at 0.16 (disbelieving), and then how he celebrates it at the end at 1.52 (pumped). Oh, and he starts running after the fourth shot as soon as he hits it (0.09), just as if he knows 'Svensson' is going to smash it into the stands.
HEAD Tennis makes Tennis paraphernalia, and Novak Djokovic is currently the fourth best player in the Men's game.
