I’m dying, literally dying. 

This is too rich. 

Here are the lyrics:

You may say is repulsive
To hang people by feet
But I have…reputation
And reputation I must keep

So you will not do the train job?
That makes me upset
You give me back my money
But we are not even yet

Everyone’s a Nishka in their own way
Everyone does torture up in space
Though not as good as I
You all yell and cry when I cut your face
Everyone’s a Nishka in their own way
In their own slightly less psychotic way

So I capture captain Reynolds
Yeah, and his pilot too
His crew gave me money, enough for one, but not two
But yes, I am thinking
That this is, too much
I’m thinking I should offer up some kind of refund 

Everyone’s a Nishka in their own way
Everyone reads the works of Shan Yu
So mister Reynolds
Why don’t we go to meet 
the real you?
Everyone’s a Nishka in their own way
You and you and mostly me and you

I’m crazy and hold grudges
And I killed my wife’s nephew
And I won’t like it when River closes her eyes and kills my crew

Everybody!

Everyone’s a Nishka in their own way
Everyone can shoot Kayleigh’s entrails
Or torture with a knife
Or stab a douchey guy
When his duel fails

Everyone’s a Nishka in their own way
Everyone’s a Nishka in their…..

SHIT!

I have no words to express how hilarious I find this.
