At my dentist's office there used to be this nasty picture of a witch with dark yellow teeth and all sorts of candy around her that was supposed to give you the idea that she was trying to convince you to do the "bad" thing and eat sweets and not take care of your teeth. I was only 4 or 5 so I took it more like you turn into a witch if you eat too much candy and never brush your teeth. It was the scariest picture ever. I still didn't brush my teeth, though. It was just a scary picture.
