US Open champ serves donuts to New York city metro commuters
Serbia's Novak Djokovic, who won the US Open this past week, served donuts to unsuspecting commuters of the New York city's metro trains. Djokovic, who clinched his third US Open title, also posed with his US Open trophy inside the American Museum of Natural History in the city. Djokovic also did the 'floss dance' with children in the rain.
