fidius.org: What's My Pirate Name? "Dirty William Kidd", it says, which I'm pretty sure isn't quite right.
I got "Dirty Sam Flint"
(You're the pirate everyone else wants to throw in the ocean -- not to get rid of you, you understand; just to get rid of the smell. Like the rock flint, you're hard and sharp. But, also like flint, you're easily chipped, and sparky. Arr! )
