Train Law in Texas
It is Texas law that when two trains meet each other at a railroad crossing, each shall come to a full stop, and neither shall proceed until the other has gone. In one of those "true facts" books there was an explanation for this law. It seems that one of the state senators did not want a law passed. To keep this particular law from passing, he attached the train law to it. He hoped that his fellow senators would discover the train law attached, see how ridiculous it was, and not pass the laws. Nobody saw the the train law attached and passed both laws. This may not be the real reason, but it sounds good. And it might explain some of the laws we have to live with.
