Disappointed with 'How to Open a Door'

This episode was all over the place, and I wish it had been more focused. Of course, you might be able to say that about most of the episodes, but I don't blame the fly-swatting episode for going into other details, because there's only so much you can say about the core topic of that particular episode.

Rather than talking about knocking on doors or lock-picking (though the part about how you could copy a borrowed key was cool), they should have elaborated further about what you could be doing with your whole body when you're opening common door types in everyday situations. The only flat door they demoed (for a legitimate and gentle opening) had a non-mechanical handle. There was a lot of missed opportunity here.
