Taken at the 2013 BNP Paribas event in New York, Rafael Nadal first invites Ben Stiller from the crowd to join him in a game of doubles during his game with Juan Martin Del Potro.
Del Potro responds by getting a little girl who looks no older than 8 years-old to join him. The game doesn't go very well for Nadal or Stiller as the young girls' fore arm smash is unstoppable!
