This guy is known as Jimmy Jump. He has a tendency for invading major sporting events. From Yahoo!: A well known Barcelona fan, Jimmy Jump has managed to evade security teams at each of the last two European Championship, he ran through the starting lane at the 2004 Spanish Grand Prix, he scared the bejesus out of Roger Federer during the 2009 French Open men's singles final, and he even took the stage during the 2010 Eurovision song contest, going so far as to gleefully participate in one performer's choreography.
