So he says, "Grandfather, are these plates clean?" His grandfather replies, "Those plates are as clean as cold water can get them, so go on and finish your meal."
That afternoon, while eating the hamburgers his grandfather made for lunch, he noticed many little black specks around the edge of his plate so again he asked, "Grandfather are you sure these plates are clean?"
Without looking up from his burger, the grandfather says, "I told you those dishes are as clean as cold water can get them, now don't ask me about it anymore."
Well, later that day, the boy offered to out and get dinner. As he was leaving the house, the grandfather's dog who was lying on the floor started to growl, and would not let the boy pass.
"Grandfather, your dog won't let me out."
Without diverting his attention from the game he was watching, his grandfather shouted, "Coldwater, get your ass out of the way!"
