Though the shark's teeth may be lethal,
Still you see them white and red;
But you won't see Mackie's flick-knife
‘Cause he slashed you and you're dead!

Jenny Dipper was a stripper;
Someone ripped her from ear to ear;
Though the knife-work was artistic,
Seems that Mackie was nowhere near!

Someone's lying near the telly,
With his children and his wife;
It's a painting done in crimson;
You could sign it “Mack the Knife”!

Ernie Goldstein was garroted
For his cuff-links and a ring;
The survivors grew to bursting;
Strange that no one saw a thing!

Little Johnnie was abducted
And they sought him high and low;
Though his parents paid the ransom,
Mackie slashed him weeks ago!

You remember that fire in Houndslow,
Twenty agents and a cat;
While they're raking through the embers,
Here's a flick-knife – fancy that!

There's a schoolgirl who's a call-girl,
With a baby at her breast;
Someone's robbed her, someone's raped her;
Someone's flick-knife did the rest!

These may seem like scary stories,
But don't have nightmares or be upset;
Still he's evil, he's a murderer,
And they haven't caught him yet!

He's a rapist, he's a [bad word] 
And they haven't caught him yet!
