I think it's true that the edge wasn't quite there. Bart's doodle was edgy, yes, and damn funny after all they did to set the joke up (eg: getting all "Austin Powers" with it before hand to keep it blocked and then suddenly blocking everything but), however, the biting wit of the spoken word was no sharper. (However, true to form, I believe there was at least one anti-Disney joke tossed in
)
