Words At The End Of Spam Messages?

Just wondering what the heck is going on with all the words at the end of spam messages I get? Here's an example from a recent one:

gumbo infusible brighton transmission chapman tofu attain wintry fifty crest immobility yank switchblade carryover don't german des darwindust fluorine chamberlain rumen narrate backplate archdiocese suppressible testate blob capella vestibule plug curbside modulus philanthrope courtier edginghumus huddle impoverish piquant comma paper quarry daniel hawaii candlelight physiochemical buxtehude sonogram preempt downtrend locomotive demagnify shipbuildingantedate actuate rhyme competitive epitaxy expel nevertheless quixote liqueur baudelaire durable institution vacant antigone heap incendiary oboist homeopathbowie odysseus high flatus emily abusable celerity parch berkowitz labyrinth confront alveolar premonitory bern dichotomy

From what I've read, they do that in an effort to evade keyword spam filters. They figure if the filter sees those words, it will guess that the message is legit email, and not dump it. Seems to have worked in your case.
