I know fifty digits of pi, although, not the fifty right after the three.
Wow that absolultely killed me too. Funniest thing I've read in a LONG time.
I know literally thousands of digits of Pi, I just have no idea where they go.
Myself, I suppose I am a big math nerd too - that is, if the mere understanding of post-graduate math means you are a nerd. I lead a normal life with a job/wife/kids and am very active, but I certainly associate best with "nerdy/intellectual types".
OKAY FINE, I'M A NERD, I ACCEPT IT, IN ALL IT'S GLORY!
