Two poems after my own heart:

Behold the ever-patient Yak,
With four explorers on his back.
He treks for miles across the snows,
Wearing a bracelet in his nose;
And when they stop to have a snack,
It's slices of the useful Yak!

And:

You cannot please the caribou,
No matter what you say or do;
He just morosely glares at you.

Both by Katrina Moore, née Hincks, an intrepid and cultured lady of the best old-fashioned kind. I must try and track down more of her writing. Found these in David Roberts' The Last of His Kind, highly recommended if mountaineering history is your cup of tea.
