I get emails like this all the time too. I think it may be an macro-level attempt to defeat Bayesian spam filters. Put lots of random words into a nonsensical message, and the recipient will mark it as junk. Keep doing it, and eventually the spam filters will start triggering false positives on non-spam messages that contain the same words, arranged sensibly. Users then need to sort through their spam folders to find the real messages, and are then exposed to your Viagra ad.
