A man went to visit his 90-year-old grandfather

 

“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,

“Cold Water, Go lay down!”
