I spent just about every Saturday throughout my middle school and high school years watching Mystery Science Theater 3000. Around that time every screen name or handle I had contained the word "Servo" in it (Servo This was my favorite) but I never had the opportunity to just go by Servo...until I found Joblo, of course. Thankfully it wasn't taken.
Though there was a small hiccup later...I had forgotten my login information and such and decided to make a different username, "Mog." I hated it and begged Joblo to help me get Servo back, and the Mighty and Merciful Joblo did just that.
I've had that avatar for a while, too...it may be time for a change.
