I'm not really in favour of storylines which center around Joey being stupid. For one thing he wasn't this stupid in the first seasons, and for another it's getting old. Yeah we know, he's not the sharpest crayon in the box, please change the record.
I bet Monica was rather pleased with Chandler though, considering his previous comments on women and the fact that he seems to watch an awful lot of porn. It must be nice to know that he doesn't want his wife to get fake boobs. However I think Chandler would have gone to her directly and told her that he found out about her alleged boob job and asked her to reconsider, it makes no sense for him to be beating around the bush this way.
Rachel trying to baby proof the apartment was kind of fun.
Phoebe's relationship with Mike took a turn for the better and then a turn for the worse. I felt bad for Phoebe, but she did make the right choice. I really liked the scenes where she went to Ross for advice and he did his best to come through for her. The friendship between Phoebe and Ross is probably the one that has gotten the least attention, aside from Rachel's friendship with Chandler. I really like it whenever we get glimpses of these ties. And Phoebe and Ross make a great pair, they are always fun to watch.
By the way, did you notice that when Phoebe said she wanted to be with someone who wanted the same things as her, Chandler cast a glance at Monica? It was probably a coincidence, but it felt like a nod to the storyline where Monica almost left Chandler because she thought he didn't want to get married.
