I'm a huge Friends fan as you guys. How about a different perspective to the show? Let's post the events, happenings or moments from the show which we as an audience know about but the Friends don't.
My contribution:
None of the Friends know that Joey wouldn't have been Chandler's roomie and this close to all of them if he wouldn't have got the apartment at the first place. If you remember, Chandler had asked another guy to move-in with him but Heckles had him leave by telling him that he is Chandler's new roommate. Only then did Chandler ask Joey to move-in instead.
