Which nationalities do you get on with best/and or least?

I'm irish and haven't met a scot that i havent liked yet. I also like spaniards because they are so easygoing and fun. I stayed a year in Germany and think are a really nice people and not boring like some say. I find Italians cocky and slightly stupid (at least the ones ive met lol). 99% of english are awesome but the private school toffs that go to my college are absolute dickheads.
