Except his JAW stays the same; he just gets sharp teeth. Anyway, I'm not sure ANY variety of geekness is strong enough that your first thought following a physical transformation is 'hey, this is just like that thing that I'm into'! For instance, I'm a big fan of the 'Doctor Dolittle' books, but if an animal said something to me inpassing, I doubt I'd immediately go 'hey, this is just like in Doctor Dolittle!' I think it'd be more like 'AAAAAH! Wha?! Huh? AAAH! Talking animal!' ...OK, so that doesn't involve physical transformation, so it's a lousy example, but it was all I could think of.
