I found an 'ook. A rubber coated 'ook. I was 'appy about it 'cos I needed an 'ook to 'ang something on. I put the 'ook in a safe place for later. An' then blow me down if a bit later on I didn't find another 'ook exactly the same! That's lucky I thought, and I went to put it in the safe place with the first 'ook.
And then, yes you have guessed it. I found the first 'ook. The original first 'ook. And as it happened, I was right about the third 'ook which I thought was the first 'ook being a third 'ook altogether.
So I now had three identical 'ooks. Well, almost identical 'ooks. I am able to tell them apart because the third 'ook which I thought was the first 'ook has got a bit of rust and the second 'ook is a bit discoloured and the first 'ook, the original 'ook which I renamed the second 'ook before I realised it was a third 'ook, is cleaner than the other two 'ooks.
All three 'ooks are now in a safe place!
