His Heart Is As Black As Coal

People have done things that make a man furious and he's losing self control.
He has become angry and meaner than hell and his heart is as black as coal.
He gave two people a place to live for free and he was treated like shit.
He was good to them and they told him "Fuck you" and he threw a fit.
One day they regretted that they said "Fuck you".
He knocked their teeth out with a two-by-four and now they can't even chew.
He punched both of those assholes really hard in their guts.
Then he beat both of them senseless and kicked one in the nuts.
He stopped taking people's crap and started getting revenge, he's making his enemies pay.
Now he makes them suffer and his heart will remain as black as coal for the rest of his days.
