That was a quite funny episode actually, they ridiculed each other for their trademark habits without really hurting anyone, ie when Ross thinks that proposing to Rachel and not remembering it sounds like something he'd do. Jack Geller's part was weird, they seem to be going for a more "American Pie-esque" humour now, what with all the farting jokes and the sex jokes were even more blunt than they used to be.
My only complaint about this season opener: By the end of 824, we were supposed to think that Joey and Rachel were going to get together since Rachel accepted his proposal, which was a complete contradiction to what had been going on since 818. Now, during the season opener, we learn that Rachel likes Joey as a friend but definitely doesn't want to marry him unless she can't find anyone better to help her with Emma and that she's been considering getting back to Ross, which totally contradicts what they wanted to make us believe with the cliffhanger.
While I and a lot of others expected something like this, all this triangle and "we don't know where this is going" nonsense over the summer was nothing but a huge media hype to stay in the press. If at any point they had seriously considered getting Joey and Rachel together that scene with Monica and Rachel would *not* have aired, it's as simple as that.
Now, let's wait and see what the review man himself, Tennant Stuart, makes of all this, once he gets to see the episode ;)
