In the apartments where we lived when I was little the drain was kind of slow I guess and the bottom of the tub would fill up with a couple of inches of dirty soapy water. I would stand as far away from the deeper end of the tub as possible because I thought evil fairies riding fish would come up through the drain and bite me and poke me with little sticks and things.
