Great thread!
I used to work graveyards in a big process plant with an intercom/PA system. We would always try to out due each other by paging each other with annoying nicknames that played off of either your name or a characteristic of of the person you paged. One night my buddy paged "RYAN NEWTY" and I heard the whole plant erupt in laughter. I hated it at first but then like anything else you get used to it and now I'm rather proud of it.
