When I was in grade 9, the whole grade sought out a way to fund our junior high grad. We had a wakeathon and during this wakeathon, we had the computer labs. I don't know how but we managed to play Duke Nukem 3D in school so we played Duke Nukem for the whole night. I needed a login name.
Now I need to let you know that, at the time, I was a huge Greek mythology geek AND a huge geography geek. So when I wanted to choose the name of the three-headed hound of Hades, I wanted Cerberus. However, being the geography geek and having a documented working memory deficit, I chose the old name of an island in Indonesia, Celebes now Sulawesi. After playing the whole night with this name, I grew attached to it. But coming home and thumbing through the daily leafing through the antiquated atlas from the 80's, I realised my error. Over the course of a year, Celebes evolved to Xelebes, just to make the connection less obvious.
