A woman on Britain's Got Talent has done what so many failed reality show contestants have long dreamed about: egging Simon Cowell live on camera, reports EW. During the show's finale today, a viola player playing as part of a backing orchestra for one of the finalists jumped out of her seat, ran to the center of the stage, and gleefully pelted eggs at Cowell as the performers continued to belt out "The Impossible Dream." Turns out, she was a contestant on last year's show. She later apologized for "overshadowing" the actual performers. (More Simon Cowell stories.)
