SYDNEY (AFP) Two Australian sisters have set an unofficial world record for continuous TV-watching after sitting through 87 hours of uninterrupted World Cup and football coverage. Football-mad Joanne and Alanah Argyrou, 22 and 24, outlasted two other contenders as they sat for some three-and-a-half days at Sydneys Star City Casino, beating Dutchman Efraim van Oeverens 86 hours. They were given one five-minute break per hour but were allowed no more than five cups of coffee a day. In between World Cup broadcasts, the women watched recorded matches and football documentaries.
