I was playing an APA league match, my opponent left the cue ball sitting in one corner, about 1/4 of the ball hanging over the pocket, and the 8 ball sitting dead in the middle of the opposite corner. I called the pocket and got down to shoot and that jackarse squatted directly behind that pocket (almost with his chin on the table) and was waving his stick and his arms and making odd noises. I resisted the urge to go kick him in the face and simply got up and told him to sit down and shut the hell up, then made my shot.
