Hundreds of grown children gathered in Washington Square Park Saturday for the city's seventh annual Pillow Fight Day. The fluffy free-for-all began at 3 p.m. and for three hours, Washington Square Park was turned into an epic and feathery battle field. The annual NYC event was organized by a group called NewMindSpace, that declared this year's Pillow Fight to be bunny-themed, in honor of Easter weekend. The pillow fight takes place in over 150 cities worldwide, and thousands participate every year. That's real war out there, Gioele Nunziatini, 24, told the NY Daily News. No alliances, nothing. Just every man for himself.
