I suppose you could say where you learned your vocabulary.
I've always assumed it was from reading extensively in dusty old tomes, rather than from being an English major at the University of Wisconsin or something.
(In my case, I got an 800 Verbal 'cause my dad's an English professor and my mom's an editor; they met in grad school, both studying English. However, people look at you funny if you use professorial diction in quotidian settings, so I generally tone it down to a plebian level. That said, I liked Gary's writing far better than the 2nd Edition written grade 6 reading level stuff.
