A dramatic and sudden bursting of the blood vessels from extreme anger due to an inconsiderate family member putting back into the refrigerator an ice tray with a single cube of ice in it.  These hemorrhages can be avoided by simply FILLING UP THE DAMN ICE TRAY or REMOVING THE ICE TRAY FROM THE REFRIGERATOR WHEN IT'S EMPTY!  It's just that simple!  Hey grandma, quit being so lazy and fill up the damn ice tray!  Please!  Alot of market research shows that grandparents are the biggest culprits of empty ice tray abuse in America.
