"I'm throwing a party, and a friend of a friend clogs the upstairs toilet. He plunges it, a little too violently, and the back of the tank hits the wall. The bottom of the tank drops off, causing all the water to come out on to the floor. He doesn't know how to shut off the water, so it continues to fill up the bathroom.
Eventually it floods into my closet, and into an air vent. From here it makes its way to two spots, my basement floor, and a nice big pool on top of my kitchen ceiling. This is when he finally tells me we have a problem, and the water gets shut off. Shortly thereafter, the kitchen ceiling collapsed. He didn't even offer to help clean up."
...the amount of ignorance in your comment speaks for itself.
