Whose side are you on? Or, rather, which side are you on?

American fan Bob Abels of Falls Church, Virginia, had no idea what was going on when a Tokyo Dome security guard told Abels to take off his shirt. Wearing the jersey of his favorite Japanese team, the Hanshin Tigers, Abels naively was headed for his assigned seat near the right-field foul pole.

"You must take off your shirt, sir," said the guard, trying to explain Abels' life could be at risk because he was entering the cheering section of the Tigers' archrival and home team, the Yomiuri Giants.
