I love that word Ïnscrutable" reminds me of a verse

The perverse sexual habits of the camel
are stranger than anyone thinks.
At the height of the mating season
He tries to mate with the Sphinx
But the posterior orifices of the Sphinx
are clogged by the sands of the Nile
Which accounts for the hump on the camel
And the Sphinx's inscrutable smile.....
