There aren't that many language puns in Open All as in TTR, and besides fans wrote English subtitles for all the episodes which makes it a lot easier to translate; when people talk in various accents it's hard to understand from hearing.
Example for a pun in OAH, someone tells Arkwrite about a dream he had:
Arkwrite: Did you recognize the voice? Whose was it?
Customer: At first I thought it must be God.
Arkwrite: Yes, well, you would at that time of night.
Customer: But it turned out to be Mr Samuelson from Gordon Street.
Arkwrite: What? Him with the horse and cart? I'm surprised you thought he was God with the vocabulary he's got! Unless he was talking about that place near Gomorrah.
Customer: Sodom.
Arkwrite: That's what I say!
Ronnie Barker is not well known in Israel, I'm not sure any of his series was ever on the main channels. But some people know him and love him, one of the rare genius actors that ever were. It's amazing how OAH is fresh and funny after 40 years, also the genius of Roy Clarke of course.
