Cleaning the Plates

A man went to visit his 90 year old grandfather in a very secluded,
rural area of the state. After spending the night, his grandfather
prepared breakfast for him consisting of eggs and bacon.
He noticed a film-like substance on his plate and he questioned his
grandfather. "Are these plates clean?"

His grandfather replied...."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 tiny specks
around the edge of his plate, and a substance that looked like dried egg yokes.
So he asked again, "Are you sure these plates are clean?"

Without looking up from his hamburger, the grandfather says, "I told you
before, those dishes are as clean as cold water can get them, now don't
ask me about it anymore!" Later that afternoon, as he was on his way out
to get the paper, the dog started to growl and would not let him pass.
"Grandfather, your dog won't let me out," he complained. Without
diverting his attention from the football game, his Grandfather shouted,

"Coldwater, move!"
