I've watched both versions and LOVED them. After seeing the British version first, I didn't think I'd like the American one, but it's hilarious too. I record it every week so I won't miss it.
My favorite (American) episode is the one where Michael burns his foot on his George Foreman grill and Dwight runs out to help him. When he hit the gate with his car and then got out and threw up on the trunk, I almost peed my pants laughing. It was just so random!
