It was the repeat tonight in US syndication.
The show when Monica threw the 'boring party' (with Rachel's mom) and Joey & Chandler have the 'fun party' (with Rachel's dad)...Remember the scene where Chandler comforts Rachel in the hallway after her speech about the 4th of July? When he passes her off to Ross when Ross opens Joey & Chandler's door was very moving for some reason.
Maybe just for me? Maybe it's because of the lack of interplay between Chandler & Rachel that this was a special scene. No matter, it was a highlight for me, and another great show that I missed the first time around.
