User blog comment:Bullet Francisco/The Origin of Your Username/@comment-4714730-20130704202923

My crappy user name of course came from Pac-Man and Sonic being my two favorite things at the time, and the 138 part came from Destroy All Humans! being my 3rd favorite franchise in which the main character Crypto, is given a specific clone number, and in Destroy All Humans! 2, the Crypto clone is marked with the number "138". That's my story, I guess.
