How did you come up with your Screen Name for the Ledge?

[DavidMn]

I thought it would be interesting to find out how you all picked your screen names for the Ledge. Of course mine is mainly my first name, but since there was already a David here, I decided on the Mn at the and because 1. the initial of my last name is M, Marx,and 2. Mn is the abbreviation for the state I'm proud to call home, Minnesota.
