I found The one With all the Scripts with the complete scripts of all seasons in both english, french, and italian. Then there is this Ross Geller site where some guy has been watching all the DVDs and is filling in the scripts of the aired version with dialog and scenes that were added on the DVDs.
It amazes me how serious some people are about their hobbies, it really does. It's beautiful though how the web lets such people share the results of all their hard labors with the rest of the world, inhabited mostly by people like myself who would never take the time out to do something like that.
