When the shark bites...

Oh the shark has pretty teeth dear
And he shows them pearly white
Just a jack-knife has Mac-heath dear
And he keeps it out of sight

When the shark bites with his teeth dear
Scarlet billows start to spread
Fancy gloves though wears Mac-heath dear
So there's not a trace of red
On the sidewalk Sunday morning
Lies a body oozing life
Someone's sneaking 'round the corner
Is the someone Mack the Knife
From a tugboat by the river
A cement bag's dropping down
The cement's just for the weight dear
Bet you Mackies's back in town
Louis Miller disappeared dear
After drawing out his cash
And Mac-heath spends like a sailo
Did our boy do something rash
Sukey Tawdry, Jenny Diver
Polly Peachum Lucy Brown
O the line forms on the right dear
Now that Mackie's back in town

-Mack the Knife. I'm not sure who the original artist was, but Bobby Darin and Frank Sanatra and a ton of other people have sung it... Anyway, this song was the inspiration for this pic.
-I call my version of Mack the Knife, Mac. Because the full name is Mac-heath, and it doesn't seem to make sense to shorten it to Mack, with a K.
-As it says in the song, Mac uses a "jack-knife". I looked up the term, and it appears that a jack-knife is basically a pocket knife. He also wears "fancy gloves".
-Yellow converse!!
-There's an elaborate back story as to the machinery hooked up to Mac's chest and head, but it's too much to write here, and I've already put way too much...
