I've always had this mystery that I want to clear up... As I speak british english, I always say the "and" in e.g. 2009, 234 etc. (two thousand and nine, two hundred and thirty-four), and I know for a fact that different english regions based on british english also say the "and". I've read on Wikipedia and they say it's apparently american english, but I was watching CNN just now and one presenter say the "and" and the other doesn't. They're all american... (CNN US simulcast on CNN International now...) so this is really weird. I guess this differs from where you're from in the US... probably also applies to the US english omitting the "on" in "on" Monday, "on" Tuesday... coz it's really weird that some articles on cnn.com have the "on" and some doesn't... if you're an american and you don't say the "and" nor the "on", where're you from (which part of US)???
