Okay, so yeah... I am obsessed with this show. It's so character-driven, I always find myself trying to figure out the personality types of all of them. The only one I'm pretty sure about, is Pam is an ISFP. She reminds me so much of my ISFP cousin.
But what about Michael? ENFJ maybe? Definitely some kind of ExFx... Jim? Dwight? ...Creed (My favorite :P)?
