I love using the word/expression, "eh". It leaked a little bit across the boarder here into Buffalo quite a number of years ago. For the 10 years that I lived out of state I would get funny looks every time that I would say it after a sentence. lol
My absolute hands down favorite though is when someone with a thick Canadian accent says the word, "about". "How aboot that game the other night?". It makes me grin every time.
