I'm thinking about in a later episode when Moncia said she's never been fired before and she was in the one five steaks and an egg plant.

Monica introduces Rachel to Chandler....but they met back in school days when Ross and Chandler went to college together!

but if you listen very carefully, you will hear that chandler says we met before.

How about Chandler with the photo thing? In TOW The engagement picture he can't smile or take a decent photo, yet at/after the wedding he has no problem!

there's tow chandler can't cry but he's "cried" before. I just got done watching tow moncia looses all her stuff in the garage due to water and jack is talking about how Ross was a mircle but in earlier episodes Ross was "an accident" before they got married!

Well there's always the two Mindy's, the two Carol's, and the two last names for Barry. That always bugged me.

I don't the two thing?

I have though of one thing, but is has to do with the series Joey. There he says he's never lived alone but he did for a while in season 2 of FRIENDS. (maybe a little of topic, sry for that).

Also, in the first episode Monica's apartment number is 5, but after that it is 20.

Anyone else every notice that when Monica is on her date with Paul The Wine Guy, she tell's him the "Underdog got away" story, but that doesnt actually happen until a few episodes later?
