Eugene Volokh relayed a funny newspaper clipping. To save time downloading the image, here is the text:
The first divorce directly related to the September 11th terrorist attacks has been filed in New York. It appears a guy with an office on the 103rd floor of the World Trade Centre spent the morning at his girlfriend’s apartment with his phone turned off. He wasn’t watching TV either. When he turned his phone back on at about 11am, it rang immediately. It was his hysterical wife, “Are you OK? Where are you?” He said, “What do you mean? I’m in my office of course!”
