In 11th grade, about a week before my then-girlfriend would break up with me, she gave me a plush Ewok, the Ewok Wicket from Return of the Jedi. That was in late 1998. The little Ewok was a bit of a frustration for me because it was a really nice gift, and then we broke up soon thereafter.
In late 1999, she and I got back together, and I discovered EN World. Times were good. I made a new screen name (my old one was from Mechwarrior 3 online gaming - Vergil17), and I decided to include Wicket. I misspelled him, though, and added an extra T. And because it was a D&D messageboard, and I didn't know how much people would end up arguing over rangers, I made my screen name a Ranger Ewok because that seemed the most appropriate class for him. Plus he was nice and heroic that way (2nd edition rangers were goody goody, remember?).
Thus, Ranger Wickett. The screen name has lasted me 5 years now.
