I once had the most intractable, weird problem I'd ever faced up to that point, no help from my colleagues (I only had one and I was very, very much more experienced in that area), spent ages trying to understand it, trying to find answers. I eventually found someone else with the same problem, in a German support forum, who had fixed it... but never explained how. There is an xkcd for this, and it felt like it was written just for me.
