I often pop down to my local rugby club

It is a pure game played by real men

I used the play on the wing

Not that I was anything special

But because I had a turn of pace

This said I have of late

Become obsessed with mathematics

Yesterday the posts and x bar were struck twice

When it was harder to hit them at all

On a bleak winters day last season

Both posts and the x bar were struck by a conversion

When it was impossible to do such a thing

I am beginning to analyse the mathematical possibilities

Ans always carry a pencil and a notebook to each game
