Can cold water clean dishes?

[DeadAddict]

A man went to visit his 90 year old grandfather in a very secluded rural
area of the state he lived in. 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 ask 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, he was on his way out to get dinner in a
nearby town.
As he was leaving, his grandfather's dog started to growl and
wouldn't let him pass so he said,
"Grandfather, your dog won't let me out."
Without diverting his attention from the football game he was
watching on TV his grandfather shouted, .
"COLDWATER, Go lay down!

LOL nice..except if the name of the dog (coldwater) wouldn't have been in CAPS it would be better because when I saw that I already knew what was going to happen. :-/

My girlfriend's dog has this same ability to convert any plate into a clean plate, however no residual film-like substances have been noticed.
