Notice how MJ conveniently tears spiderman's mask at the last second, allowing him to eat her? Seriously, ever tried to eat a ham sandwich through a spandex mask? It's pretty tough. For that matter tearing a spandex mask is pretty tough as well... I call b.s. spiderman would have to remove his mask first!

For that matter, how come getting bit by a zombie in the marvel universe gives you a magical gum-less face with razor sharp teeth in a matter of hours?
