Simon Cowell is best known for critiquing acts on his ITV talent shows, but on Saturday the TV mogul became part of one.
The Britain's Got Talent boss provided assistance to Ben Blaque, a crossbow performer from Missouri, for the finale of the American's dangerous act.
Simon rang a bell on the stage so that a blindfolded Ben could hear where to shoot at a target, which set up a chain reaction that eventually pierced an apple on the top of the American's head.
David Walliams joked: "You had an opportunity to kill Simon Cowell and you blew it."
As Ben received four yeses, Alesha Dixon told him: "Ben, you are hot. You take a shot, and you definitely hit the spot."
Fans watching the action unfold could barely believe their eyes. Many took to Twitter to express their incredulity.
