To clear this up: Google considers which words are used to link to a site, not only words that appear on that site. Thus, the few times "more evil than satan" appeared on the web, it linked to a page with a very high page rank: Microsoft's. Once the news spread, the news stories themselves achieved a higher search rank than the uncommon link and high-ranking Microsoft page had alone. Google has since tweaked the way it combines these factors to prevent such odd-ball results from appearing in the future.

At an info session with a Google developer, we were assured again and agin that it would be well-nigh impossible to introduce an intentional easter egg into the Google engine, since something like an additional string comparison for every query would have a massive performance impact over the millions of queries Google handles.
