This episode is my favorite because:
it showed us the typical Friends moments we like;
it is so funny that you can cry of laughing;
so many laugh-out-loud moments;
amazing acting from all of the actors;
great storylines for all of the characters;
amazing setting-Las Vegas;
so funny last scene and one of the all time best clifthangers;
I watched this episode few years ago and I was so exciting after its end and last scene with Rachel and Ross was amazing and one of the most unforgettable moments of Friends for me personally.
We are all in favour of the writers for making this gift for us.
The greates years of Friends.
