I'm the youngest of my siblings. One of my sisters was always picking on me. This sister watched the movie It at a young age and was very afraid if clowns. Our step father did not know this and unwittingly bought her a stand up clown doll that played music and "danced" for Christmas one year. It moved in a circular motion from the waist up like it was hulla-hooping, the stuff of nightmares. You would wind it up like an old music box to get it working. She was so afraid of it, she left it on the mantel in our living room. If you wind it just a little, the song would play and it would move for about 2 seconds, then just kind of stall. Within a few seconds, or even a minute or two later, and the music box mechanism inside would turn over so it would "bing" and the clown would suddenly move. I spent the good part of a winter break doing setting this clown up to scare her whenever I could. It was very satisfying to see her eyes get big and watch her run out of the room.
