Cold water

John went to visit his 90 year old grandfather in a very secluded,
> rural area of Georgia. 
> 
> After spending a great evening chatting the night away, John's
> grandfather prepared breakfast of bacon, eggs and toast.  However,
> John noticed a film like substance on his plate, and questioned his
> grandfather asking, "Are these plates clean?" 
> 
> His grandfather replied, "They're as clean as cold water can get them.
> Just you go ahead and finish your meal, Sonny!" 
> 
> For lunch the old man made hamburgers.  Again, John was concerned
> about the plates as his appeared to have tiny specks around the edge
> that looked like dried egg and asked, "Are you sure these plates are
> clean?" 
> 
> Without looking up the old man said, "I told you before, Sonny, those
> dishes are as clean as cold water can get them.  Now don't you fret, I
> don't want to hear another word about it!" 
> 
> Later that afternoon, John was on his way to a nearby town and as he
> was leaving, his grandfather's dog started to growl, and wouldn't let
> him pass.  John yelled and said, "Grandfather, your dog won't let me
> get to my car". 
> 
> Without diverting his attention from the football game he was watching
> on TV, the old man shouted ... "COLDWATER, GO LAY DOWN!!!!"
