Okay, I've been mostly a lurker, but have seen ALL the posts (and made a few myself) on the Ross/Rachel or Rachel/Joey scenarios.
I've got it!
I just got done watching TOW Monica/Phoebe/Rachel looking through a girlie magazine of Joeys (funny line was Phoebe "OH for the days of going out to the barn, taking your top off, and bending down like that!") and then one of them said "I'd date her, she looks like fun" and Monica asks "If you had to date one of us, who would you pick" and Rachel and Monica both say they don't know. Phoebe however, pipes up right away with "I'd date Rachel". They go on the rest of the show with Rachel being "a pushover" and Monica being too high maintenance.
Wouldn't it be hysterical if Rachel and Phoebe got together!!
Haha!
