Digger Malcolm ...

... There I was, a-digging this hole
A hole in the ground, so big and sort of round it was
There was I, digging it deep
It was flat at at the bottom and the sides were steep
When along, comes this bloke in a bowler 
which he lifted and scratched his head
Well we looked down the hole, poor demented soul and he said 
Do you mind if I make a suggestion? 
Don't dig there, dig it elsewhere
Your digging it round and it ought to be square
The shape of it's wrong, it's much too long
And you can't put hole where a hole don't belong
