Why do ``thy'', and ``thine'' sound so odd when used in modern English? Is it simply that we're used to using the plural ``your'' and ``yours'' in their stead, or is there some other aspect of the language missing that makes them seem odd when used without it. As an example: ``I'll pluck thy cock if I may eat some of it with you.'', or ``On second thought, my cock is meater than thine, perhaps we should share it instead.'' both sound rather odd to me.
