He took a tremendous left cross right in his left eye and it
knocked him
out - just
one punch. Folks hauled him up to his room to sleep it off, but he never woke up - died right there in the room.
Since then, no one was able to sleep in that room because of the ghost. One day, a barmaid needed a room. Grandpappy said, "Sorry, miss, I've only got one room left and its haunted." "That's ok, I'll take it," replied the barmaid.
