A wife was very worried about her husband's bad habit and
one night she decided to give him a fright. She draped herself in a white sheet and went down to the local cemetery, knowing that her husband was in the habit of taking a shortcut through it on his way home. It was not long before he came staggering along, and out she jumped from behind a headstone.
"Ooooooo!" she wailed, "I am the Devil!"
He sticks out his hand... "Put it there, pal," he says, "I am married to
your sister."
