Joshua Halley, an eighth-grader at Millvale Middle School, consumes alcohol at a 12th-grade level, sources reported Monday. 'This precocious youngster shows a drinking aptitude far beyond that of the average 13-year-old,' Millvale principal Charles Meckler said. 'Beer, wine, vodka, whiskeyJoshua can handle them all.' Meckler said that upon high-school graduation, Halley can expect a full scholarship from his choice of the nation's top party schools.
