My experience has been that quite a few graduate stuidies programs can be coerced into considering your application, especially if you have appropriate life experience that translates well into core necessities of the advanced field of study. You could also probably audit much of the advanced coursework under the guise of an undergrad acceptance to a university, and then convince the professors that you are a genius. And if you really happen to be a genius, most of the undergrad courses can simply be tested out of for credit.
I knew a girl in college who was possessed of an eidetic memory. She was sooo hot, she was carrying a triple load, 45 units of credit where the normal load was fifteen. I wouldn't really call what she was doing education, though. It was more like filling an empty bucket with a bunch of old books.
The other option, forged or stolen transcripts are relatively easy to procure if you are ambitious enough. But if you didn't want a bachelors, why would you want an advanced degree?
