I wish I had saved the results every time over the last few years that Google showed me a page it claimed had what I was looking for, when neither searching the visible text or even the source code of the page produced any such string. I am sure that it's happened to me hundreds of times by now, if not thousands. For a long time, it was surprising and ranged from annoying to infuriating. Now I just sigh and accept it as the cost of Googling.
