A cousin, who was a few years older than me, once informed me that anything flushed down a toilet was stored in the tank on the back, then removed at night by a man who went around to each house and emptied the tanks with a vacuum cleaner. It was important, she warned me, that I should never go to the bathroom at night, lest I be caught there when the toilet man came and have my butt sucked off by the vacuum.
I was not convinced, but I knew that telling her she was wrong wouldn't go over well, so I don't know how long she went on believing that one.
