This is something that you really won't "get" if you aren't part of the ninetndo generation.
Coincidently, Bear just sent me an email on an unrelated subject that said nothing more than "up up down down left right left right b a start." I wonder if references like these will ever make it past the internet and into more of a mainstream inside joke.
I think back to when I read Hamlet for the first time. A large portion of the the text was actually footnotes explaining the esoteric and nuanced humor of Shakespear's day. Will weird video game references work their way into the culture such that in the future people will look back and wonder, "wtf is the konami code and why is it in my classical literature book?"
