I married your sister
Jane was tired of her husband coming home drunk, and decided to scare him straight. One night, she put on a devil costume and hid behind a tree to intercept him on the way home. When her husband walked by, she jumped out and stood before him with her red horns, long tail and pitchfork.
“Who are you?” he slurred.
“I’m the devil,” she answered.
“Well, come on home with me,” he said. “I married your sister.”
