I turned my nickname into my legal name.

I have a nickname at the dojo, it's not oft used but it's

(insert legal name here) _____a'nator.

I showed up for a ride and introduced as "here's _____a'nator"

Some were shocked. I'm 5'1". BTW I did not get the nickname by being vicious, I got it from a simply horrific e-mail fauxe pas (sp?) of global proportions
