Yes, humor is different in different countries but here is another question : does humor have absolute measure? I mean, saying that in my country humor is better than in the others.... I don't know if this statement could be correct. I like one type of humor, you like another. Who can tell us which one is more humorous? And even if one said that humor in your country is better than in mine, would I really care? Nope, because I enjoy what I enjoy. That's why I think we can't quantify humor according to some kind of " humor scale ".
Just think so.
By the way, when I moved to live in a foreign country, I thought that its humor was the stupidest humor in the world)))
