If you're thinking about the final episode of the original run, it's important to know:
* There was no "last episode" in the sense of a conclusion to the show's storyline. The show simply ended its run after several seasons.
* It's impossible to say exactly what happened in the "last episode" without knowing which one you are asking about. You would need to specify the season and episode number.
If you are referring to the "Mind Your Language" reboot that aired in 2006, then the final episode, titled "The Reunion", included:
* The return of several original cast members, including Barry Evans, who played Jeremy, and Carmen Silvera, who played Mrs. Fanshawe.
* A reunion at the language school, where old memories were revisited and new problems arose.
* A humorous and nostalgic finale for the show.
If you provide more information about the specific "last episode" you're interested in, I can give you a more detailed answer.
