Was amused to see this item on New World Notes about Kingdom of Loathing... I don't play it myself, but it's where my name comes from, as (bad) luck would have it.
What passes for my mind, you see, went blank when I realised I had to make up a name for my Second Life avatar; as it happened, an idiot friend of mine was around at the time, and he suggested... the name of his KoL character. So that is how I came to be called Glorf. (My friend has a long and silly explanation of why his character is called "Glorf Pwlg", but I really haven't the strength to get into all that right now, and anyway it is extremely distasteful.)
We had been leafing through the recently published (at the time) reprints of the "Steel Claw" comic strip that day, and when I paged through the last names, I chose one in honour of the creator of the Claw, hack SF writer and editor Ken Bulmer. And that's how I became the Brady Bunch - wait, I'm not the Brady Bunch. Pity. That name would have been almost sensible.
After all, I thought, it didn't really matter, I would just poke about this whole SL thing for a little while, see what it was like, and probably just let it drop when I got bored with it....
Well, that was March 2010, and here I am, still not bored yet.
I'm not sure if there is any moral to this story, except maybe "think about your name, you may be stuck with it for longer than you think", and also "I need to start hanging out with a better class of people". (He doesn't read this, don't worry.)
