I actually read an article about this a few weeks back. A bunch of guys got together and just abused google's ranking system to get their search terms at the top of the field. They say it started out as a small gag that they posted on another board, but then 100's of people started pitching in with links from their sites to increase the rankings.
Type in "Mad Cuckold" you'll notice she's number three and counting for the miserable failure search.:cof: Really that is the most awful expression I have seen on anyone's face. Ever.
