Apart from a few poems we had to memorize at school, I don't usually try to. But I had the most boring job one time which involved dipping copper wires into a solder pot all day. The lead fumes were probably going to my head so that might explain why I decided to learn AA Milne's Forgiven:The Alexander Beetle Poem, to wile the hours away.
I found a little beetle; so that Beetle was his name,
And I called him Alexander and he answered just the same.
I put him in a match-box, and I kept him all the day ...
And Nanny let my beetle out -
Yes, Nanny let my beetle out -
She went and let my beetle out -
And Beetle ran away.
