I was thinking about how through the internet we all have a level of anonymity, so basically to everyone I met or talked to, I was a nobody. I took the name "Mr.Nobody" to state myself as THE nobody.
I later replaced the b to a ß to bypass the old /spy and /fetch functions that required a full name to work, only to find my original name taken in ALL forms less than a week later after the novelty wore off.
My name was not from the movie as I had the name first (roughly 2007).
