Nopal mix fully chalk?

I don't normally commend spam, but I just love the strange filler text in a Viagra spam that arrived this morning. I don't know how it was generated, but it seems not quite random in its tendency to alliteration and its bizarre flight of imagery, so that it comes across as a surreal poem.

I see others have a similar reaction: see Ode to the SpamBots and Poetry from today's batch of spam mail. These all put me in mind of Dylan Thomas's How soon the servant sun:

How soon the servant sun,
(Sir morrow mark),
Can time unriddle, and the cupboard stone,
(Fog has a bone
He'll trumpet into meat),
Unshelve that all my gristles have a gown
And the naked egg stand straight,

Sir morrow at his sponge,
(The wound records),
The nurse of giants by the cut sea basin,
(Fog by his spring
Soakes up the sewing tides),
Tells you and you, my masters, as his strange
Man morrow blows through food.

All nerves to serve the sun,
The rite of light,
A claw I question from the mouse's bone,
The long-tailed stone
Trap I with coil and sheet,
Let the soil squeal I am the biting man
And the velvet dread inch out.

How soon my level, lord,
(Sir morrow stamps
Two heels of water on the floor of seed),
Shall raise a lamp
Or spirit up a cloud,
Erect a walking centre in the shroud,
Invisible on the stump

A leg as long as trees,
This inward sir,
Mister and master, darkness for his eyes,
The womb-eyed, cries,
And all sweet hell, deaf as an hour's ear,
Blasts back the trumpet voice.
