Not exactly only in my country, but I was talking to some people a while back and realized something, there's a TV show that absolutely everyone in Spanish speaking countries (and Brazil) knows of, and has watched over and over again, it's so ubiquitous to us that the closest comparison in terms of how known it is that I can think of would be The Simpsons. However the show never broke the language barrier (except, like I mentioned, to Brazil where it was translated to Portuguese). So imagine going somewhere and realizing you can't make Simpsons references because these people have never heard of the Simpsons. By this point I think every Spanish speaking person knows what show I'm talking about, but for non-spanish speaking people the name of the show is El Chavo del 8 (which translates to "The boy from the 8th" as in the boy that lives on number 8, the implicit joke is that he's so poor he doesn't even have a name, which sort of got ruined by translation because in Brazil he's named Chaves)
