A guy starts a new job at a coal mine and is wandering around with a mine veteran until he gets his bearings.
He looks around the mine, getting to know his wsy around, greeting the workers and so forth.
By lunchtime, he gathers with the rest of the men in the cafetaria. By this time he's covered head to toe in coal dust, but is told to only wash his hands and not shower for lunch.
After all, he'll just end up covered in dust again.
At the end of the day, the workers all gather in the showers, and get undressed.
The new guy looks around and sees even the naked men are covered entirely in coal dust.
"It's the same every day. The dust gets under your clothes and covers everything," the supervisor says.
The new guy looks around some more and notices one guy is covered in dust like the others, but there's none on his penis.
He brings it to the attention of his boss.
"Oh, that's Fred," he explains, "Some days he goes home for lunch..."
