Murtogg: These characters are under copyright by Walt Disney.
Authoress: I'm terribly sorry, I didn't know. If I see him, I shall inform you immediately.
Jack: Apparently there's some sort of a high toned and fancy sequel being filmed, eh? How could it be that two supporting characters such as yourselves did not merit an invitation?
Murtogg: Someone has to make sure PotC characters stay off limits to fangirls.
Jack: It's a fine goal to be sure but it seems to me that a… a fangirl like this makes no money anyway, really.
Murtogg: Ah, this song looks quite harmless, true enough, but there's no fan that can match the mouse for greed.
Mullroy: Oh, and no fangirl that's not possessed by the damned and inspired by a plotbunny so evil that hell itself spat it back out could possibly have a desire to take on the mouse, therefore couldn't be writing fanfiction.
Murtogg:No.
Mullroy: Like I said… there's no sane girl that would write this.
Murtogg: Hey! You! Get away from there.
Mullroy: You don't have permission to write, Miss.
Authoress: I'm sorry, it's just ... it's such a pretty plot – film.
Mullroy: What's the purpose of this song here, my good girl?
Murtogg: Yeah, and no lies.
Authoress: Well, then, I confess. It is my intention to commandeer the characters, pick up plotbunnies in Tortuga, write, scribble, blunder, and otherwise let my weasely black fantasies out.

Slap him well!

Once my boat he stole
in the dead of night
now I've caught this fowl
by his trinkets bright.
Bells he'll soon hear ring
I'll hit him left and right
watch his head-adornments spin
and celebrate tonight

Slap him well, slap him well
strike him on the quay.
Captain's head rocks to the side,
dreadlocks spin away.
Slap him well, slap him well
strike him on the quay.
Captain's head rocks to the side
dreadlocks spin away

He will apologize
and he'll make amends
or I'll treat his face
all day with my hands.
Should also like to spank
till his bum is hot
red like father christmas' coat
can't lie down in his cot

Slap him well, hard like hell,
jingling, trinkets fly
oh what fun it is to slap
left, right, either way
slap him well, hard like hell
jingling, trinkets fly
oh what fun it is to slap
left, right, either way
