SPiN World Championships

Ping-Pong masters like Jan-Ove Waldner (three-time World Champion and Olympic gold medalist) and Mikael Appelgren (four-time World Cup champion) go paddle-to-paddle for this two-day battle at SPiN New York, Susan Sarandon's 13,000-square-foot table-tennis club. If the flying balls make you dizzy, focus on celebs like Scarlett Johansson, Oliver Stone and 50 Cent, who've been known to make their way here. The June 24 event is black tie, so dress in your most dapper attire.
