Pr nightmare? The only nightmare here is your IQ level.
There are actually 2 reasons why that would have shown up...
1. It's automated based upon the keyword you searched for which is an ad function within Adwords
2. They did it to raise their ad quality score in which their URL is shown twice as we'll as was approved by the Adwords team.
The only bad PR here is for your blog and your lack of knowledge.
