Jeffery Scrotum Bag Barnes? Oh man that is pure gold. Totally worth being fired over.
I remember I used to get stuck doing data entry of mail in requests for catalogs at a company I worked for. I hated doing it, so to make it more fun I'd make up weird variations on the names when I entered them. It started when I got mad that I couldn't read anyone's name because they wrote it so illegiably. All I can remember is Bob's Small Engine Repair became "Billybob's Hillbilly Garage".
I never really had the balls to put something totally offensive like "Scrotum Bag" in there though. I gotta say I would have been laughing my ass off if that came to my mailbox. I mean, what harm is there really?
