The Unconcerned Widow
An old man and woman were married for years, even though they hated each other. When they had a fight, screaming and yelling could be heard deep into the night. He constantly told his wife in front of all the people in the town: "When I die, I will dig my way up and out of the grave to come back and haunt you for the rest of your life!"
The neighbors believed he practiced black magic and was responsible for missing cats and dogs and strange sounds at all hours. He was quite feared and enjoyed it very much.
Then the man died abruptly under strange circumstances and there was a closed-casket funeral. After the burial, the wife went straight to the local bar and began to party as if there was no tomorrow. Her neighbors approached in a group to ask if she wasn't worried about her husband digging himself out of the grave.
The wife put down her drink, smiled and said, "Let the old bugger dig. I had him buried upside down!"
