When I was a bachelor, I lived by myself

When I was a bachelor, I lived by myself,
And all the bread and cheese I got I put upon a shelf;
The rats and the mice did lead me such a life,
That I went to market, to get myself a wife.

The streets were so broad, and the lanes were so narrow,
I could not get my wife home without a wheel-barrow:
The wheel-barrow broke, my wife got a fall,
Down tumbled wheel-barrow, little wife, and all.

Moral:
Provide against the world, and hope for the best.
