I used this worksheet with my Elementary adult students and they really enjoyed it. This episode is the one with Brad Pitt, and Thanksgiving dinner. There are so many things to exploit, phrases, etc. And it's also a good laugh.You can adapt it to make it appropriate for your students' level. As a post activity I asked them to imagine that they were at a high school reunion and they had to use some of the phrases they heard as well as some of their own, and they got really into it.
Tip: some of my students had never watched the show before, so it might be a good idea to bring some pictures or flashcards to introduce the characters.
