A woman whose husband often came home drunk decided to cure him of the habit. One Halloween night, she put on a devil suit and hid behind a tree to intercept him on the way home. When her husband came by, she jumped out and stood before him with her red horns, long tail, and pitchfork.

"Who are you?" he asked.

"I'm the Devil," she responded.

"Well, come on home with me," he said, "I married your sister."
