Tennis tomfoolery between women's world number three Maria Sharapova and men's number two Novak Djokovic is the subject of YouTube's most-watched sports video of the day on August 1, accumulating close to 1 million views after 48 hours online.

At the 2012 Wimbledon Championships in June, Djokovic conspired with sports brand HEAD for a courtside prank, pulling a golf club instead of a tennis raquet from his bag. The company counts both Djokovic and Sharapova among its sponsored athletes.
