As they do in many episodes, the writers here skillfully parody standard potboiler dialogue--Monica's "unfaithfulness" to Rachel is treated in the manner of a soap opera confrontation between boyfriend and girlfriend ("Really, Rachel, I was thinking of you the whole time. Look, I'm sorry, all right? I never meant for you to find out"), and Joey's confrontation with the Bijan cologne cowboy is treated in the manner of a cheesy Western, complete with slo-mo action, grunted dialogue, and the requisite ride (or in this case, walk) into the sunset. And let's not forget the charming "saloon" scene when Chandler, in the manner of a spaghetti Western bartender, serves the depressed Joey a box of juice.
The breast milk scenes, while not following the same pattern, are nonetheless original (can't think of another show in which breast milk is actually sipped!) and well-written. All in all, a well-balanced episode giving each of the "Friends" memorable lines.
