Carving Set Knife

There once was a fly on the wall
I wonder why didn't it fall
Because its feet stuck
Or was it just luck
Or does gravity miss things so small?

God's plan made a hopeful beginning,
But Man spoilt his chances by sinning;
We trust that the story
Will end in great glory,
But at present the other side's winning.

An elderly man called Keith
Mislaid his set of false teeth -
They'd been laid on a chair,
He'd forgot they were there,
Sat down, and was bitten beneath.

A flea and a fly in a flue
Were imprisoned, so what could they do?
Said the fly, “let us flee!”
“Let us fly!” said the flea.
So they flew through a flaw in the flue
