From Winter Winks 221: Timber!

The morning was quiet and peaceful and calm:

To John, the respite was a much needed balm.

As he'd worked half the night

To save a girl's sight,

He was tired right down to his toes and his palms.

Thanks to the Doctor, the girl had been saved,

Her parents so grateful they ranted and raved,

And while John was quite glad

For the luck that they'd had

A long sleep was the thing he most craved.

Mary shooed away every curious guest,

Each fled at the lady's most ardent behest.

As each of them knew,

Like all good couples do,

For her Doctor she did always her best.

x x

Holmes himself stayed away for the day

Preferring instead to experiment with hay,

And wait for his friend

To come round the bend

So they once again might join in the fray.

When lunch time came, the Doctor still slept;

Seeing this, his wife's heart rejoiced and leapt.

He at last got the rest

That he so needed, lest

He should fall ill himself and become quite inept.

But as Mary sat down to drink her hot tea

She heard a crash. "Oh, what could that be?"

Really quite stumped,

To the window she jumped

To find out what caused the untimely melee.

She sighed. Of course! It was the month of December,

So the neighbour boys, were were ever so limber,

Found a most massive tree

And, as glad as can be

Brought it home with a thundering, bellowing "Timber!"
