Yeah, like David said: Spammers use this method so that the email doesn't 
contain all the pure marketing buzzwords that a spam filter usually looks 
for, but also words that typically might be found in a non-spam words. 

If the poetry (for example) outweights the marketing buzzwords, then the spam 
might get a lower score than usual.

Or another attempt is to insert some random text, or poetry, or plain garbage 
words which make no sense in any language and at the bottom of the email is 
an URL which leads to a page where the real product or service is advertised.

Someone looking at the nonsense email might then be tempted to click on the 
link to see what this is about.

However, these kind of spams with URLs in it are also facing a harder time 
since the introduction of the SpamAssassin plugin 
Mail::SpamAsssassin::SpamCopURI.

That plugin checks email bodies for URLs, extracts the host and domain name 
and checks one or more "special" RBL blacklists (like sc.surbl.org) which 
contain lists of domains used in SPAM for advertising purposes.

This plugin even catches the spams that contain nothing but a promotional URL 
in it and the text "Check this out!" - for example.
