I've read some long time ago something about the stories of a sys admin complaining about their LUSERS
It was something like the bastard sys admin or something like that.
Do you have a link from the original history?
EDIT
Thanks for the link.
What's the story ( history?? ) behind BOFH.
You're thinking of the Bastard Operator From Hell (BOFH), and his sidekick the Pimply Faced Youth (PFY). Enjoy :)
YUP its BOFH and everything can be found here

and earlier stuff here

The BOFH on the register is very funny, but, the very early stuff is by far the best.
The full archives are on Simon's site here.
