A you man has just arrived for his introduction to his new job in a coal mine and is being shown around by the boss.
When they pass the showers in the afternoon he notices that all the men are covered from head to toe in coal-dust - completely black.
"Does that happen every day?" he asks
"Yes" replies the boss. they don't bother showering for lunch since they're just going to get covered again anyway.
Then he notices that one man, like his colleagues, is also covered in coaldust except for his willy, which appears to be completely clean.
"What about him?" he asks.
"Oh, he goes home for lunch."
