A word to the wise ain't necessary - it's the stupid ones that need the advice.
The Ballad of M. T. Nutt and His Dog
by Andrew Barton Paterson
The Honourable M. T. Nutt
About the bush did jog.
Till, passing by a settler's hut,
He stopped and bought a dog.
Then started homewards full of hope,
Alas, that hopes should fail!
The dog pulled back and took the rope
Beneath the horse's tail.
The Horse remarked, "I would be soft
Such liberties to stand!"
"Oh dog," he said, "Go up aloft,
Young man, go on the land!"
