My mother always use to tell me and my brother when we were kids, "Don't do anything bad, or i'll get the screw driver. You know what happens after that? I'm going to unscrew your belly button and your butt will fall off." So I tried my best to be a good girl (never was of course) and so did my brother. To her knowledge, her theory worked, until my brother got into trouble and she said that line. He gave her a look and said, "Not-uh! 'cuz I tried that and it didn't work!"
