Until I was around 7, when my mother was angry with me, she'd pick me up and dangle me upside down over the toilet. Usually, it was for something like getting a 95% on a test instead of a 100%, or some such thing. Anyway, she'd tell me that I was stupid and that she should flush me down the toilet. Obviously, I wasn't very bright, because I'd believe her and scream and cry until she put me back on the floor.
