When I was young my parents misled me into believing that there were creatures known as 'belly button monsters', and occasionally showed me dead specimens that had been washed out of my father's belly button after he had had a shower. At one point diagrams were even drawn of the creatures in an attempt to convince me. Why my parents did this I'm not sure, but to this day I don't trust belly button fluff, just in case it is alive.
