Novak Djokovic irresistible in Head.com ad

Serbian tennis star Novak Djokovic, the world's third-ranked player behind Rafael Nadal and Roger Federer, gets extremely loose in his first major outing for sports brand Head since the equipment and apparel company signed him in January. His nickname's Djoko, with a silent "D," and he's certainly more fun on camera than Federer, whose performance in that '70s-themed Gillette ad with Tiger Woods and Derek Jeter was as wooden as an antique racquet. In the Head spot, there's a cute set-up with Djoko going into the stands mid-point for some over-the-top flirtation with an attractive fan, and still having time to return his opponent's shot.
