The Aussie accent has always amused me. Second to that would be German then French. I suppose I've grown numb to the accents of mid-America, as I cannot distinguish most accents anymore, save for obvious foreign ones reigning from the general area of South-East Asia and the Middle Eastern to Euro-Asian areas. They stand out considerably. Otherwise, I've heard plenty of English accents before, only at the airport however. Jamaican on occasion and South of the border accents have a similar sound which sadly leads to the stereotype most people from Mexico or otherwise are, well, Mexican. Bah, rambling.
