Right the real thing, write now:
It's snowing on the seventeenth
Day of Octopus Gardener Month,
For the Roman Imperium
Nomenclature garrison kept
Inside a castle's wall-mounted
Parapet, or some such word
From med-evil arch-tech
Thanks Merlin, for giving
A gratitude and a sorrow
On the even of that Farce God,
Love, lorn and shorn for ocean
Mid-sections, whose bottoms are
A whale, tale'd from inside
And where we are, you and me (and you),
There is frozen cornflake rain
Spreading tidings of nigh-est moons
Roman Ryan
