A fellow's wife was very worried about her husband's heavy
drinking 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
from the pub. 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."
