 * 1) I know that they're professionals, but still, as you can see from bloopers in multiple movies and TV shows, it takes a lot of effort to get into character for one role, not to mention for multiple roles in one episode. I'm just as impressed by them as I feel sorry for them.

I'm not convinced it's so easy but they do bounce off the other actors which helps. Kevin Conroy often mentions it is much easier when other actors are present so perhaps that helps a lot.
