Some years ago, one of the St. Paul, MN newspapers ran the following story as a news item: {ed But also quite probably an urban legend...} A recently-married young couple were getting dressed for work one morning and were in foul humor as the result of a just-ended spat. The wife had trouble with the zipper of her dress and finally asked her husband to zip it up. He grabbed the zipper and said "Zip, zip, zip!" as he yanked it up and down, wrecking the zipper of her best dress in the process. That did little to promote wedded bliss but they finally went off to work. When the wife came home from work that afternoon, she saw her husband working under his car parked in the driveway with just his legs extending from beneath it. As she walked by, she grabbed his zipper and said "Zip, zip, zip!" as she jerked it up and down. Feeling smug and pleased with herself, she walked into the house but was horrified to discover her husband standing in the kitchen drinking a glass of water. "Who was that under the car," she gasped. "Oh, that was our neighbor, Joe," he replied. Then she had to confess what she had done and asked him "What do we do now?" After a moment's thought, he said "Well, we'd better go out and apologize and explain the situation to him." So they went out and called to him but got no response. Looking under the car, they discovered that he had been so startled that he had reared up, knocking himself unconscious, and was bleeding heavily from a deep cut on his forehead. There the story ended, but I suspect that the couple had some difficult moments while trying to fix that embarrassing situation.
