In Friends Season 01 Episode 07 "The One with the Blackout" in this scene, it seems that Ross says something to Paolo in Italian. From the context it seems he is asking "Do you understand?".
A few script sites have that line written as:
ROSS: Yeah! Se vice?
For some reason they have the English bit wrong because Ross clearly says (assuming the Italian isn't also wrong):
So, do you erm... se vice?
However I put "se vice" into Google Translate and it didn't translate from Italian. Is Ross trying to speak Italian here? If so, what is he actually trying to say?
Also, what's the joke? The audience laughs when he says it. If the joke was that he had got the Italian wrong, surely most people watching wouldn't know that.
Update: I checked the subtitles on Netflix and it was spelled “ceviche”, but same problem - that doesn’t translate either.
