There's also the budding euro-English, which is kinda funny because it is to some extent the revenge of all the words we've stolen from other European languages and then slowly turned into false-friends.

Anyway as an American I'm always in favor of just giving our language away to anyone to do whatever they want with it, really just go nuts, especially -- throw some z's in there, they really add some pizzazz to the language. (Just ignore the British, they will try to get you to change them back to s's... but you can see what that does to the pizzazz!).
