Maybe that is because the Argentines are the subject of so many jokes in South America? I didn't realize that until I went to dinner one night with several people from Latin America - some from Mexico, Brazil, Venezuela, and Argentina. One of them got on a role, telling one "Argentine joke" after another. I even felt uncomfortable. Apparently, the rest of Latin America thinks that Argentines think they are better than the others (more European blood), and all of the jokes center around this self-assumed superiority. As an example:
Argentine son: "Father, when I grow up, I want to be just like you!" The father swells up and says "Oh, why is that?" The son replies "so that I can have a son JUST LIKE ME!"
I've heard a description of Argentines as Italians who speak Spanish, think they're British, and act like the French. I had an Argentine Spanish teacher in college. One time she corrected me on my (mis)pronunciation of certain Spanish phrases. She criticized me for pronouncing them with an American accent. I had to hold my tongue as her English, though quite fluent, was pronounced with a very heavy Argentine-Spanish accent.
