Viral Video: Djokovic, Serena dance Gangnam style on court

The Australian Open begins on Monday, but Novak Djokovic shelved conventional preparations for a while, warming up for a shot at a third consecutive Australian title with a bit of weekend hit-and-giggle and a Gangnam Style dance with Serena Williams.

That was for kids' day, when thousands of people flocked to Rod Laver Arena to see 2012 Australian champions Djokovic and Victoria Azarenka hitting in a just-for-fun match with players including past champions Roger Federer and Serena Williams, a cast of human-sized cartoon characters and a marching band that played the tune to Michael Jackson's Thriller.

Come Monday, the No. 1-ranked Djokovic will be back to work, hoping his opener against Paul-Henri Mathieu is the first of seven matches this month at the venue where he's had the most success in Grand Slam tennis.
