In reply to Removed User:
I googled 'camel hump' and came up with:
The sexual life of the camel,
Is stranger than anyone thinks.
This weird and mysterious mammal,
Had designs on the hole of the sphinx.
But the hole of the sphinx is covered,
By the shifting sands of the Nile,
Which accounts for the hump on the camel
And the sphinx's inscrutable smile.
