Scary Tales

From the text:

Well, one day Mr. Hall was there and Grandpa started into one of his scary stories. There was a
piece of wood burning in the fireplace, sort of sticking out, and Pa spotted it. I watched him put his tobacco way back in his mouth so he could get a good long shot. At just the right moment in the story, he threw his head forward and that tobacco came out and hit that wood just right; it fell off on the
floor and the fire sparked up. Somebody threw a baby on the floor, men ran out, and Mr. Hall ran out too. When he passed us, Mr. Hall’s scalp was as naked as the palm of my hand. Jesus have mercy! Granddaddy scared the hair right off Mr. Hall’s head! Well, I went over to his chair, and there in Mr.
Hall’s hat was his scalp! I picked it up. “Grandma! Is this Mr. Hall’s rug?” Grandma said, “Put that thing down and go wash your hands.” Oh, I loved those days when Grandpa told his scary stories.
