Commandeered from penknife

You post a topic, list, category, whatever, in comments. (examples: "Five Times Bruce Banner Lost His Toothbrush," or "Five Ways Nikola Tesla Failed to Take Over the World"). I'll answer with a list of five things.

Please stick to fandoms you have a reasonable expectation that I'm familiar with - otherwise, I will feel free to make up answers that might or might not actually make any kind of sense.
