Dark as a Dungeon (TBBT S8E6)

Come and listen you fellows, so young and so fine,
And seek not your fortune in the dark, dreary mines.
It will form as a habit and seep in your soul,
'Till the stream of your [bad word] as black as the coal.'

 [bad word] 
Where it's dark as a dungeon and damp as the dew,
Where danger is double and pleasures are few,
Where the rain never falls and the sun never shines
Where it's dark as a dungeon way down in the mine.

It's a-many a man I have seen in my day,
Who lived just to labor his whole life away.
Like a fiend with his dope and a [bad word] his wine,
man will have lust for the lure of the mines.

I hope when I'm gone and the ages shall roll,
My body will blacken and turn into coal.
Then I'll look from the door of my heavenly home,
And pity the miner a-diggin' my bones.
