Americans these days love to rubberneck. When there is a car accident, you are guaranteedto see a rubbernecker. Dane Cook does a bit about accidents, and how Americans love to watch the "actions." He refers to a man standing on the corner saying that he was in his kitchen when he heard a bang, so he grabbed his slippers and went out side; then another man says he was in the living room, and he didn’t even grab shoes. I admit to rubbernecking myself. When I see a car accident, I love to try to see what is going on. It applies to more than accidents though. In a restaurant one day I heard a couple arguing, and being the rubbernecker that I am, I listened closely. I then began to notice the other people around doing the same.
