A child went to visit his 90 year old grandfather. While eating the breakfast of eggs and bacon prepared for him, he notices his plate isn’t clean. 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.”
Later that day, they went out to get dinner. As he was leaving the house, the man’s grandfather’s dog who was lying on the floor started to growl and would not let him pass.
His grandfather shouts, “Cold water, get out of the way!”
