Ghosts

Ghosts were just scary things! If a funeral was going past and you pointed a finger or two at the hearse, there was only one sure-fired way to stop the ghost from haunting you!
That was to put into your mouth at once, all five fingers of the offending hand!
Or was it all ten fingers? The moral of this story? Always keep your fingers clean, especially if you see a funeral procession headed your way!
