On a hairdryer my mom had when I was little I saw a tag with the usual warnings including this one: "WARN CHILDREN ABOUT THE DANGER OF DEATH DUE TO ELECTRIC SHOCK" My parents did a good job of this obviously.....

My opinion:
When designing the bathroom, one should not locate any receptacle on the same side of the room as the tub or shower unless it is greater than 6 feet away from the tub or shower. Since most dryer cords are 6 feet, this would fix the problem.

But what about the sink?
Shocks through an energized sink are probably less likely to be fatal due to the reflex reaction that would occur when someone put their hand in the sink that was energized. Mechanically (ease of escape) and electrically (less contact surface area) the sink scenario is less dangerous. It would probably knock you on your butt though and you could kill yourself by whacking your head....

Oh well.... you can't save every idiot. Natural selection WILL occur and there's no way to stop it.
