A Knife for a Knife

I challenged myself to write a story poem in fifty words or less
I teaches one to be consice and, although I could have expanded this ad infinitum, I found it difficult to get it done with so few words but a very rewarding experience it was. Have a go yourself! :-)

 
Had over yer wallet Paki git
Or your fuckin’ throat I’ll slit

Ah you’ve recovered
Since I used my knife
Well enough to threaten life

You takin’ the piss or what?
Give, quick, the fuckin’ lot!

Taking the piss? Certainly not
I was your surgeon John
When you were shot
