To give teenagers a break from general English classes over the Xmas season. Watch the episode with subtitles with intermediate- advanced students (with advanced you can leave out the subtitles). I would recommend watching the episode first in case you want to change or adapt the worksheet depending on your class and students. Particularly it touches pronunciation issues with Spanish speakers and the words "look" and "Luke" you could use that as a starter to go into pronunciation with more detail after the video.
