Heh, reminds me of the "Brenda Utthead" Dilbert comic.

When I set up the email system for our group, I did the first-of-first-plus-last which resulted in normal-looking email names like "TFabris". But our corporate overlords have a different scheme for their email system which is much more amusing. First five letters of last name followed by first two letters of first name. Somehow this results in some very funny names:

Tod Bouris: Bourito
(With beans and rice, he's a combination plate.)

Tony Fabris: Fabrito
(When my friend Chris saw that on my return address for the first time, he cracked up and started saying "yo soy el Fabrito! Arriba! Arriba!")

Eric Brooks: Brooker
(Clearly the hard boiled cop with a stained past, but he's got a heart of gold)

David Yarwood: Yarwoda
(Mmmm! Today backwards talking we are!)

Etc.
