Here is something for you to do when bored. Go to Google and enter "Failure" as the search and let it go.
Check out the first link in the list (and have a little chuckle). (Or click on this search link)

Then notice the Google Advert displayed on the right hand side and you should see an explanation link.
In case it is no longer there, you can also direct to the page that explains why here.

There must be an awful lot of people somewhere with too much time on their hands. I can bet that the conspiracists will still try and say that someone has paid for this campaign. Do a search on the phrase "Googlebombing Examples" and some more should turn up.
