todd: in the movie 'chicken run' the two rats use some language that i think you might know something about. at one point, the one rat calls the other 'norbert', as in, "...you stupid norbert..." and another time he says, "...why are you crying, you nancy?..."

i assume that using those names is a lot like calling someone a nerd or dork and a girl, but where does this come from? am i right in my assumption --- kind like using 'waldo' as a name for a nerd?
