Plug it in somewhere, throw it a number, and it'll wordidize it, e.g. it'll turn 671 into "six hundred seventy one".

BTW, I already know how much more elegant and efficient the lot of you could have made this, so if you really want to be efficient, there's no need to say so. :-p

_{But I know that you will, anyway, but that'll just prove that you're not so efficient after all! And I'd still win! Bwahahahahahahahahahaha!}
