Colin Scot (anyone else remember him?) used to say that American English was the only language where you could rhyme "romance", "dance" and "trousers".(Substitute "pants" for the last, and switch on a Brooklyn accent)

There are a couple (at least) of American/English lexicons around, at least one very light-hearted. They used to use them when running induction courses preparing English employees and managers to work in the US. That it was (1980's) considered necessary to do so says a lot.

I, for one, am glad that such differences exist and that the cultural holocaust of worldwide US TV, films and music hasn't eliminated them. Vive la difference!
