Just saw one the other day. I forget which show it was, guy had a really nice buck at about 25 yards and shot over his back. They went through the whole I can't believe I missed that shot thing for about 5 minutes. They then went on to explain that if you watched the shot in slow motion you could see a small twig that the shooter failed to see. In the slow mo replay you could clearly see the twig and you could more clearly see that he didn't hit the twig and deflect his arrow. He muffed the shot period.
