Thanks Chris. It's from Robert Burns' delightful poem, "The Twa Dogs". Hector and Luath are the dogs in question.
"And wearie at last wi' monie a farce,
They set themselves upon their arse,
And so began a lang digression,
About the Lords o' all creation."
Or something like that. And so begins a long discussion about life and the human condition between the two weary canines. But since I only have one dog in the hoose I limited my title for contextual accuracy.
