New Zealand's naked rugby team, the Dunedin-based Nude Blacks, lost for the first time in its nine-year existence on Saturday, beaten 25-20 by a clothed women's team from Spain.
But there may be a clue as to how the visitors did so well. In the spirit of friendly competition, the ladies promised that for each try they scored they would remove an item of clothing.
Asked if they had let the visiting Conquistadoras score a few easy tries, Brad Henderson, a 23-year-old student, replied: 'Of course.'

But the offbeat game became more popular every year and now the Nude Blacks play an invitational side before every international rugby game in Dunedin.
