Summary: Joey falls in love with Phoebe's twin sister Ursula to Phoebe's dismay. Phoebe lets it happen but has second thoughts afterwards. Chandler struggles to fire a co-worker who he is attracted to and ends up asking her out instead, making it more awkward when he has to break the news to her. Ross gets doubts of being a father after attending Carol's Lamaze classes. Rachel forgets to take off the Christmas lights and falls from the balcony while trying to take them off.
The Good: This was another very enjoyable episode, though it was an evident step down (see: The Bad). Each of the storylines were very enjoyable. Phoebe and Joey's story is set up for more payoff and was a fine storyline which I enjoyed. Ross attending the Lamaze classes was fantastic though as Ross continues to have hilarious interactions with Carol and Susan. There were loads of laughs and it ended with a great moment of Ross beginning to realize the responsibility he is about to take on. Ross would have definitely been the character of the episode, but he was one-upped by Chandler's equally wonderful storyline. His "firing" of Nina was hilarious and the situation continuously getting worse was very funny. Chandler has so far been the MVP for this season as he consistently delivers whenever he is given a major storyline.
The Bad: This episode wasn't as good as others in the season though, and I think it was because of the two part structure. By having only set up here and no pay-off (with the exception of the Chandler story), it gave the episode a sower pace and there were fewer jokes because of that. I think the Joey storyline suffered the most because of this as there was a noticeable drop off in joke quality for that storyline. This could have been squeezed into a single episode. The Spanish TV story wasn't very funny and simply felt like padding.
Best Moment: Chandler dropping lies after lies in hilarious fashion. Though it is closely contended with Ross at Lamaze class.
Character of the Episode: Chandler.
Conclusion: This was a solid episode of comedy, but a disappointment when compared to the other episodes this season. The two part structure is likely to blame as comedy storylines are often weaker when stretched through multiple episodes.
