Or a question you had years ago. Couldn't find an answer. So you did a workaround and/or forgot about it.

Now you hit the same problem search -- and find you original question. But wait! Now there are half-a-dozen other people with the same problem! So you click on all of those links.

But none of them could find an answer either. Bonus points if there's a guy who comes in condescendingly and quotes a manual or some other standard piece of information -- which is also wrong. This is usually because they didn't pay enough attention to understand the question in the first place.
