Back when I was in high school, a friend of mine had a French foreign exchange student staying in her house. He was quite amused by our "ow" and "ouch" (if I remember correctly, the equivalent French pain noise was something like "aiee").
And just as we make fun of Canadians for saying "eh?", they make fun of our "huh?" — it sounds like a goose being rogered, according to my friend Monica.
Last night, there was a fellow from the Netherlands playing on my Armagetron server. He wrote in excellent English, but when he came out of a really tight race against one of the AI lightcycles, exclaimed "fjiew!" It took me a couple of seconds to realize that it was the Dutch spelling of "phew!"
That's what's so neat about the Internet. Not only can you play games against people halfway around the world, you can actually learn trivial things while doing so.
