There is this very nice couple
Who pose to be no trouble
Introducing Mr. Bull and Mrs. Cow
You will get to know them somehow
She is like your mother
And he is like your father
They started up a good business
With a product to help avoid sickness
Their method is quite simple
And might appear rather fickle
The bull and cow meet
In a very intimate greet
A donation is given by Dad
Something he just has to add
It is a very special seed
Delivered at a mighty speed
Before long a baby does come
It comes
