What's the deal with your nickname? How did you get it? If your nickname is self-explanatory, then tell everyone when you first started using the internet, and what was the first thing that made you say "wow, this isn't just a place for freaks after all?" Was it a website? Was it an email from a long-lost friend? Go on, spill it.
Years ago, a close friend of mine showed up to work wearing a greek fisherman's cap. I asked him if I could try it on. Upon wearing the cap, other co-workers declared that I looked better in the cap than my close friend did. My friend conceided to that point and ended up giving me the cap. From there, people started calling me Captain.
