Memorizing Pi With Mary

On a dark day of no homework, Mary was free.
She went into the rain with her sheep; back then, she had three.

Where road comes to river, the path forms a joint.
Hearing baa-ing and bleating, she rushed to that point.

A bad little lamb thought the mud looked like fun,
A cold, tired, wet Mommy-sheep trailed the muddy one.

The ewe slid after the lamb, in the growing downpour,
It landed on the bank with Mary’s flock, making four.

But the naughty lamb slipped; Mary started to run.
Into the river it vanished, she sloshed after that one.

She dragged it up onto land shivering;  when it began to revive,
she dashed home through the rain with a big flock of five.

With sheep safe in their shed; bathed, warmed, and dried, Mary was fine.
Stew’s good in bad weather; but better is pie! Mary’s mom had made nine.

As the grey daylight drifted to black, Mary’s chastisement came due.
Her parents formed a diameter round her, taking turns between the two.

Her mother stormed: “Rain and rivers, what bad choices she picks.
Her father calmly replied: “The farmer will claim his lost sheep here at six.”

But the farmer surprised them, “Due to brave Mary, they still are alive”.
“She may keep them. Now, her growing flock will have five.”

So, we come full circle to the next day she was free.
That naughty lamb alone was more work than her three.
