"Has a streaker ever scored? And would it count if they did?"

Well Jimmy, the self-proclaimed 'World's No1 Streaker,' Mark Roberts, from Liverpool, has scored at least two goals while baring all. Roberts, who has also streaked at the Super Bowl and Royal Ascot, scored in the Liverpool v Chelsea Carling Cup game at Anfield in 2000 and the 2002 Champions League final, between Real Madrid and Bayer Leverkusen.

At Anfield, Roberts took a pass from Gianfranco Zola before beating the entire Chelsea defence and firing past a half-hearted Ed de Goey, after hurdling the perimeter fence. His goal bonus: a magistrates court appearance and £100 fine.

In the Champions League final, at Hampden Park, he ripped off his velcro suit before stealing the ball, running past two defenders and finding the aptly-named Leverkusen keeper Hans-Jorg Butt no match for his finishing prowess.

Roberts is not the only streaker to find the back of the net. In December 1998, during an interruption in Reading's 1-0 win over Notts County, a fan ran on to the field, kissed the ground and scored past the County keeper before evading a steward and disappearing into the crowd.

These goals didn't count because they occurred during breaks in play (both of Roberts' efforts came during the half-time interval), but even if a streaker were to find the net during a game, it wouldn't count.

Law 10, The Method of Scoring, says that a goal can only be given if no infringement has been made by the team scoring the goal. A streaker would be an ineligible player; a team cannot field more than 11, so there would be no goal. And that's even before considering improper kit! The referee also has the power to stop the game if "an unauthorised person enters the field of play".
