My dad used to tease me and say that if you took the plug out of the bath tub while you were still in it, that you would get sucked in with the water.
I can't remember the number of times he had me in frantic tears trying to pull him outa the bath when he pulled the plug out in order to wind me up! Fun now maybe, but back then I thought he'd be sucked up and eaten!!! Very traumatising if you think of it!
