I have a little friend of eight

I have a little friend of eight
Who stays with us each year
Bringing with him when he comes
His bonny, sunny smiles.

His jokes, we laugh,
His football, we gasp
As he kicks it straight through a rose bush
His grasp of snakes and dinosaurs
Amazes every one

'Ask me a question on snakes,' he says.
We struggle to find a question
That he cannot answer
But no succeeding is possible.

He did a swim for wild life
And he would love to climb
The mountains he has learned about.

But his leg that leans against the wall,
His cold, hard, leg
Doesn't climb or bend at all.
