When I was little I was not the kind of kid who asked their parents every question imaginable, I would figure out life's questions by myself. One of these questions was what the noise the toliet made when it flushed.
I figured that an evil witch and some goblins lived in the toilet. I believed that whenever the toilet was flushed that I had to shut the lid, turn out the light, run out of the bathroom, and slam the door shut all before the toilet stopped flushing. I thought that if I didn't then the evil witch would send her goblins to get me and they would cook me for dinner.
I don't know why I thought this but it scared the hell out of me for years.
