Novak Djokovic bounces the ball on the ground so many times before serving because he dreams of being a well known and well liked player. He does so many impressions of other players, using their trademark habits and hope one day he'll be famous enough for other players to make fun of him. He just wants a "thing" like Nadal's many, many things, Federer's hair flicking, Roddick's tongue and Agassi's walk. This is a cry for attention and he's getting it now. Good job Novak, people are talking about you.
