I liked that episode, except for the Andy subplot as everyone else has pointed out.
I loved Jim's deadpan delivery of what was obviously sarcasm, but which seemed to go right over Dwight's head. I also liked the Dwight and Angela story and how it ended. Dwight looked so happy when he learned he was truly a father, that was a good moment. The only part I didnt like (besides Andy) was the Jim and Pam ending. Too sappy. It doesn't feel genuine anymore.
