I have prepared this one for teenagers. I often use the following link for making my own worksheets http://www.imdb.com/title/tt0583612/ There you'll find quotes, plot summaries, goofs. And there is the link for watching the episode itself with subtitles. http://watch-friends-episodes-free.blogspot.com/2015/01/friends-8x06-one-with-halloween-party.html . Task one is to complete the dialogues and task 2 is to put the sentences into the right order. I usually do the tasks before watching to make my students predict the right answers and then we watch to check up. Enjoy! (For intermediate students: you may practise reported speech with the help of it too.)
