Does anyone know of any episodes (other than the ones mentioned below) where the Friends were in two obvious groups? And if so, what were the groups? Cos I've noticed that they're sort of split into two halves - firstly, intelligence (this isn't necessarily true, just what the normal view of them is before you get to know the characters a little better) Phoebe, Rachel and Joey are the not--so-intelligent ones, and Monica, Chandler and Ross are the intelligent ones. Secondly, in TOW Five Steaks and An Eggplant, they split into the same two groups (except this time it's with money/without money) Thirdly, in TOW The Kips, the group thinks about splitting into two groups (well, Phoebe, Rachel and Joey do, at any rate).
Anyone know of any other episodes where this sort of thing happens?
