When I was little I always believed that bathtubs had spiders in the drain, because I saw the "legs" in the "whirlpool" of water rushing down the hole. I would always be afraid they would come out when I opened it, so I would open the drain and then quickly jump out of the tub and hope it couldn't climb out of the tub... how stupid. I'm not even scared of spiders anymore.
