When I was in 9th grade I was on the Bible quiz team at my church. Our team was called the "Aliens and Strangers." I think its from a verse in 1st Corinthians or something. Anyway, we went around saying Nanu Nanu like from Mork and Mindy or whatever. So that's when I first got my aol screen name, and I use it for most everything. That's the Nanu.
The 57v is from my maiden name. It was commonly mispronounced "Heinz," like the ketchup with 57 varieties. I ended up being fascinated with the 57V in middle school, and that became my tag (the thing you mark/deface property with). I didn't really deface any property, but I'd doodle on my book covers and stuff. Well, I did carve my tag into a cafeteria chair at a school in Germany, but it was already covered in other tags.
So that's the Nanu and the 57v
