Diff'rent Strokes - an episode with some french language in it

[dummytree]

There's an episode in which the whole family is planning a trip to Paris, I think. They're using a french learning method with records (not tapes, records!).Do you remember what episode it is? I believe it's from 82-83, around that time.
I never got to watch that one in its original form, just the version dubbed in french .They changed the contents (because characters are speaking in french, they couldn't be learning it, right?), so they're going to Rome, I think- and they're learning italian instead...I remember it was so obvious that Willis was saying "excusez moi" at some point. I"d like to watch this episode, it would be fun to hear their french
