Whilst driving around recently a friend and I got stuck at a railroad crossing waiting for a freight train to go by. To pass the time, we began speculating on the meaning of a sign we saw on some of the cars saying DO NOT HUMP. We conjectured that this might be some sort of safe-sex campaign organized by the railroads in the wake of the AIDS crisis, but eventually rejected the idea. So we put it to you, Cecil — what is the meaning of this odd instruction?
— Gene W., Dallas
Sad to say, I knew exactly what it meant before I read the article.
