A young man went to his grandfather’s place to stay for the weekend. He was sitting down to lunch when he noticed that the spoons and forks were not so clean. He asked his grandfather,

“Are you sure you washed it properly?”

“As clean as cold water can get it.” replied the grandfather. So the young man shrugged and started eating. The next day at breakfast he noticed that the plates were dirty and grimy.

“Are you sure you washed it properly?” He asked.

“Clean as cold water can get it.” was the reply.

The man, a bit suspicious, looked at his grandfather and started eating. As he was leaving, his grandfather’s dog jumped out in front of him, growled, and generally blocked him from going forward.

“Coldwater, leave the boy alone!” shouted the old man from inside.
