I'm not the first person to observe this phenomena, but I thought I'd tell you about it anyway. In a spam message titled "Re: critical an orgasm is just the beginning" the bottom of the email contained these lines:

and behind him were red sorrel and white horses. then i said "what are these my ?" the angel who talked with me said to me "i will show you what they are." so zebulun did not drive out the inhabitants.

This is most likely random text lifted from somewhere meant to fool spam filters (hence me looking at it in the first place), but it's proof if anyone ever needed it of the Tristan Tzara/Biron Gysin/William S. Burroughs "cut up" method. Technique so good, even machines can do it.
