Water...not just for the birds

Why do I keep getting yelled at for bathing in the water bowl? Isn't that what it's there for? My little feet get dirty and they need much more than my tongue can offer them.
My brother keeps getting yelled at over the water bowl too, although, he isn't bathing in it.
He is just throwing in all of his (our) toys and spraying water all over the floor and walls.
What's really fun is to watch when Daddy puts ice cubes in the water bowl. Poor dumb Jack just sits and stares at the ice cubes like they are aliens about to attack. I, on the other hand, am not quite so naive. I know they are really a project in mind control. How else could you explain a normally energetic cat just sitting in one place for such a long time, when they are not sleeping. It's unheard of. The good thing is that Jack actually leaves me in peace until they are all melted. It's great.
