Continuing the "No real import" tone of this thread...

Putting icing on cake is a stingy way of making the cake last longer by preventing loss of moisture.

Alternately, it's an effective method for loading more chocolate onto your dessert.

And if you like moist cake,, Dr. Bill, and icing prevents loss of moisture, why wouldn't you want the cake iced? Seems akin to saying "I hate getting wet" and tossing out your brolly at the first sign of rain.
