This is a really good episode overshadowed by one of the best episode next in line(The One with The Embryos).
It starts of with Alice and Frank who request Phoebe to be their surrogate.
This is obviously a big decision and consults her friends who are willing to offer full supports but only after she really thinks about this. So she consults her birth mother and Phoebe Sr gives Phoebe Jr a cute little puppy so that she would know how it feels to give up something you love. Phoebe adores the puppy and realizes its impossible for her to give the puppy away. However when she gives the puppy to Alice and Frank, she realizes that her happiness lies in their happiness and is ready carry their baby. However the ending is awkward with Phoebe Sr demanding her puppy back. Ross gets Joey a job in the museum as a tourist guide though he doesn't know a squat about dinosaurs (in his own words). However it comes up that there is a divide in the cafeteria with white color scientist sitting together and blue blazered tour guides sitting together, and Joey visibly feels upset when Ross doesn't sit next to him. While Joey,(the sweet guy that he is) doesn't seem to mind as he is used to the hardship in the acting business, Ross feels horribly guilty and decides to bring about a revolution of sorts by requesting Joey to eat with him in the middle and it leads to funny chain of events. Chandler is afraid of being able to satisfy Katie as good as Joey could (though its all in his head) and asks Monica and Rachel for suggestion and Monica draws the erogenous zone map and in one of the funniest Monica Moment, she and Rachel feels fully satisfied totally creeping out Chandler. In the last scene Katie comes all the way and thanks Monica and Rachel.
The funniest scene of the episode according to me is when Chandler botches a joke about Joey's blue blazer and Ross,Monica and Rachel though totally aware of what he meant mocks him and he ends up looking like an idiot. Lisa Kudrow proved why she is such a terrific actress in this episode like many other.
