who knows the mith story of "ALL I KNOW IS I KNOW NOTHING"?

I think this was a statement made by socrates to the oracle (priest like) at Deplhi.

The story goes..once upon a time there was a bald fat man named socrates (or Sox as his Homies would prefer) sox set out to find out who the most wisest of all is (access to the magic mirror was to the highly privileged in those days) for this he went to a temple like structure at a place called Delphi to meet the Big Dawg, the Oracle. the Oracle told poor ol sox that he was the wisest..to which the humble homey reiterated "all i know is i know nothing" or something along those lines, thereafter he sets out to prove the Big Dawg wrong and its a really lenghty account to reproduce here..but the gist of it all is that his knowledge of his shortcomings is what made him the wisest

Socrates, the blithering moron he was, forgot a little something - how do you know you know nothing if you know nothing?
