My mother has this rhyme:

It was springtime in the Rockies,
And the snow was raining fast.
A barefoot man with clogs on
Came slowly whizzing past.
He turned a straight crooked corner
And saw a dead donkey die;
He pulled out his pistol to stab him
And the donkey spat in his eye!

We've never thought of writing stuff down, we just pass it on to our own kids - and anyone else who'll listen!
