Geoff Huish, 26, was so convinced England would win the Six Nations opener that he told fellow drinkers at a social club, "If Wales win I’ll cut my balls off", it was reported yesterday.
Friends at the club in Caerphilly, south Wales, thought he was joking. But after the 11-9 victory over England, Huish went home, severed his testicles with a knife, and walked 200 metres back to the bar with the testicles to show the shocked drinkers what he had done.
Staff phoned the emergency services and put the testicles in a pint glass filled with ice cubes.
Huish, who has a history of mental problems, was taken to hospital where he remained in a seriously ill condition.
