How I remember it :-

I found an old stocking
And filled it with lead
And hit an old codger
Right over the head

The Policeman came running
And asked me my name
And I replied to him
With a Bicycle chain

The Judge said sit down son
And brush off your tears
You're going to Borstal
For a couple of years

My Mother was crying
My Sister was too
My Father was laughing
And so was the Screw

Theres bars on the windows
Theres bars on the doors
Theres bars on the toilet
Thats nailed to the floor
