Our bathtub drain didn't have the little metal strainer in it, it was just a hole. It made this horrible sound when draining, it got worse as the water level dropped.
When I was 4 or 5, my older brother came into the bathroom just as I pulled the plug. He told me that sharks could come up into the tub since we didn't have the strainer in there. I remember telling him he was full of it, but I never pulled the plug again until I was out of the tub.
Now I tell my kids that the strainer is there to prevent shark attacks.
