I'm pretty sure I got this from Mudcat--don't know specifically who:

You may not know that vehicles sold in the US have "black boxes", similar to those in planes. The National Highway Safety Admininistration has been checking the black boxes in vehicles after accidents fatal to all the occupants. They've uncovered a fascinating pattern. In most states the last words spoken in the vehicle are usually: "Oh, f---".    But in Texas, Alabama, and West Virginia the last words are:   "Here, hold my beer and watch this."
