Mine is not really funny but....
In 2007 I got my first xbox after graduating high school. After three months I finally got internet. Friends were waiting on me to play Call of Duty: World at War with them. Started it up and thought the treyarch logo was cool. Realized I need to finally set up a live account to play, when it got to user name I thought long and hard (that's what she said) and added the arch from treyarch to the first part of my name Dillon.
Thus, the birth of ArchDill
