Not long after my parents allowed me to see the movie Gremlins. (I begged for weeks, I was about six or seven...) I made up in my mind that when you flushed the toilet (these were the old style with like, what forty gallons of water in them) and were alone in the bathroom, that it set off an alarm. The evil Gremlins would come up through the toilet and get you. This being absurd because water was a problem for them in the movie. I cannot tell you how many un flushed toilets I left, or how many times I ran really fast from bathrooms!
