What is the spammer's strategy behind listing dozens of random "benign" key words?

I just received a spam e-mail with a link to something spammy, followed by several paragraphs of “benign” keywords.

Is the strategy here to teach my junk mail filter to associate these “acceptable” words with spam, so legit messages start getting flagged as junk and encouraging me use less restrictive mail filtering in the future? Or is it trying to “hit” a possible “whitelisted” word and thereby slip through the junk mail filter? Is it something else?

Here’s an example of a couple paragraphs:
“tractor tortellini bath saw magic house art weasel curve adapter tank stop sign newsprint priest knickers freckle dock pin denim tachometer kite gate blade smash increase mitten restaurant face temper disease community fibre boy hamburger raft copy delete lycra africa banana workshop furniture sea goat doctor”

“sarah kangaroo skirt dashboard kenneth brace lunch windscreen priest payment apparatus pyramid polish beech approval nest case cocktail backbone locust weasel brazil age fired owner sudan block coke celery ketchup tree crawdad gander education umbrella cd law spot bangladesh handsaw”
