Fun Fact

In Victorian times, there was an intense fear of being buried alive.  So when someone died, a small hole was dug from the casket to the surface, then a string was tied around the dead person's finger, which was the attached to a small but loud bell hung on the surface of the grave.  If someone was buried alive, they could ring the bell and whoever was on duty would go and dig them up.  Someone was on duty twenty-four hours a day -- hence the "graveyard shift."
