NEW YORK --
A New York college student celebrated his freedom from school by freeing himself from his pants at graduation. During the ceremony at Yankee Stadium-- NYU grad William Lopez took off his trousers and ran around wearing his graduation gown, boxers and shoes. As he rounded third base and headed for home, a security guard tackled him. Lopez says it was an act of "happiness and spontaneity." He was arrested for trespassing at his own graduation.
