I've seen all sorts of strange names since I used to be a case worker for the department of family services, but the saddest thing I ever saw was a teenager named "Baby Boy". I couldn't believe the parents (or grandmother, actually, since she had custody) were too lazy to name the child. This young man played for the high school football team. Can you imagine the football announcers at the game : "And it's an interception by Baby Boy...".
I asked the grandmother why he was never named, and she said when he was born her daughter was on drugs and didn't care, and it would cost a fee if she wanted to change it now! I mean, really!
