《史记·七十列传·李将军列传》
李广外出打猎，看见草丛中有块石头，认为是老虎就向它射去，射中了石头，箭头都射进去了，过去一看，原来是石头。
广出猎，见草中石，以为虎而射之，中石没镞，视之石也。
Li Guang went out hunting and saw a stone in the grass. He thought it was a tiger and shot at it, but the arrow hit the stone and was buried in it. When he went over to have a look, it turned out to be a stone.
