Improv Everywhere’s Black Tie Beach 2012

Location disclosed Fri 17; for details, visit improveverywhere.com. Only penguin suits and formal gowns will do for Improv Everywhere’s Black Tie Beach 2012. Join this swanky flash mob as it stages its third annual shorefront ballyhoo—past outings went to Coney Island and the Rockaways—and covertly tapes the reactions of unsuspecting sunbathers. Since you will swim in your finery, organizers suggest wearing a bathing suit underneath your duds and packing a change of clothes.
