This amazing World Record was accomplished on October 16, 2004 in Warsaw, Poland during the Third Annual World G.B Championship. The competition was between Lisa Sparks and two other women. One of them was the previous record-holder, who smashed only 759 men in a day.In addition to referees, six cameras were used to carefully record the event!
