I speak some odd American Midwestern language where "crayon" is pronounced "cran", milk is "melk" and double t's in words are disregarded in pronunciation.

But really, I don't need to speak any other language than English where I live. I speak a little Spanish, but there's hardly a considerable Spanish speaking community here that I would need to communicate with.

EDIT: I almost forgot, in one point in my life, I learned Hawaiian because I used to live in Hawaii. But I was so little that any Hawaiian is long gone from my mind. Hawaiian Pidgin is also important to learn, and something that sticks with you for a while, even if it is a dialect and not a language.
