They're always about viagra (or V1A G RA), or watches, or some other silly thing, and over the past few years or so I guess spammers have been trying to pad their spam emails with enough text to make a spam filter sometimes think it's legitimate.
You should try reading them, sometimes -- seriously, sometimes they read like some weird, fucked-up version of a poem.
So, in this vein, I present to you today's example, the poem "lilliputian trephination." (Seriously, the passage of text actually had a title and everything.)
by the Internet
Slaveholders signed it,
lincoln's interpretation wheels sank
into the snow the entire body of the ranscomb's daughter.
i know hera truly charming tone,
and miss marple understood
its meaning perfectly.

the noise of the horses' hoofs the mountain.
Should the house be taken,
all hopes the stony path.
But there was no need of a torch.
bones of a gigantic animal somekil.
