A man was in the hospital very ill and heavily medicated. He lost control of his bowels and soiled his bed linens. Poor fellow was so embarrassed, he gathered the soiled sheets and threw them out the window where they fell atop a slightly drunk fellow wandering around below. The drunk fought violently to escape the sheets and a security guard saw the commotion and asked "Hey, what's going on there?" The drunk replied, "I don't know but I think I just knocked the shit out of a ghost"
